It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity. In this guide, I will explain the easiest and most secure way to connect your Linear account to Antigravity IDE via Composio Connect, so it can create a new bug for team Mobile, add a comment to issue LIN-123, list all cycles for the Design team, and more without ever putting your account credentials at risk. ## Also integrate Linear with - [ChatGPT](https://composio.dev/toolkits/linear/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/linear/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/linear/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/linear/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/linear/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/linear/framework/codex) - [Cursor](https://composio.dev/toolkits/linear/framework/cursor) - [VS Code](https://composio.dev/toolkits/linear/framework/vscode) - [OpenCode](https://composio.dev/toolkits/linear/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/linear/framework/openclaw) - [Hermes](https://composio.dev/toolkits/linear/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/linear/framework/cli) - [Google ADK](https://composio.dev/toolkits/linear/framework/google-adk) - [LangChain](https://composio.dev/toolkits/linear/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/linear/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/linear/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/linear/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/linear/framework/crew-ai) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows. - Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses. - Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need. ## Connect Linear to Antigravity ### Connect Linear to Antigravity Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute. ### 1. Open the MCP Config Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor. ### 2. Get your API key Go to the [Composio Dashboard](https://dashboard.composio.dev/~/org/connect/clients/) and copy your API key. ### 3. Add Composio to mcp_config.json Paste the following configuration into the file: ```bash { "mcpServers": { "remote-composio": { "serverUrl": "https://connect.composio.dev/mcp", "headers": { "x-consumer-api-key": "your-composio-api-key" } } } } ``` ## What is the Linear MCP server, and what's possible with it? The Linear MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Linear account. It provides structured and secure access to your team's issues, projects, and workflows, so your agent can perform actions like creating issues, posting comments, managing attachments, organizing teams, and automating project tracking on your behalf. - Automated issue creation and management: Instantly create new Linear issues, update existing ones, or archive issues to keep your team’s backlog organized and up to date. - Commenting and collaboration: Post comments on issues, facilitate team discussions, and keep everyone in the loop without manual effort. - Attachment handling: Add or download attachments to and from issues, making it easy to share files or reference important documents right from Linear. - Team and cycle insights: Retrieve all teams, fetch cycles (sprints) by team ID, and get default issue parameters to help your agent contextualize and optimize planning activities. - Personalized workspace access: Identify the current user, fetch their profile information, and tailor actions or queries to individual team members for smarter automation. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `LINEAR_CREATE_ATTACHMENT` | Create attachment | Creates a new attachment and associates it with a specific, existing Linear issue. | | `LINEAR_CREATE_COMMENT_REACTION` | Add reaction to comment | Tool to add a reaction to an existing Linear comment. Use when you want to programmatically react to a comment on an issue. | | `LINEAR_CREATE_LINEAR_COMMENT` | Create a comment | Creates a new comment on a specified Linear issue. This action modifies shared workspace data and is not reversible — confirm the target issue and comment content before executing. | | `LINEAR_CREATE_LINEAR_ISSUE` | Create linear issue | Creates a new issue in a specified Linear project and team, requiring team_id and title, and allowing optional properties like description, assignee, state, priority, cycle, and due date. All UUID parameters (state_id, assignee_id, cycle_id, label_ids, project_id) must belong to the same team as team_id. The created issue's id is returned in data.id — capture it for use as parent_id in sub-issues or follow-up operations. No template_id field exists; expand templates manually into title and description before calling. | | `LINEAR_CREATE_LINEAR_ISSUE_RELATION` | Create issue relation | Create a relationship between two Linear issues using the issueRelationCreate mutation. Use this to establish connections like 'blocks', 'duplicate', or 'related' between issues. | | `LINEAR_CREATE_LINEAR_LABEL` | Create a label | Creates a new label in Linear for a specified team, used to categorize and organize issues. Label names must be unique within each team. If a label with the same name already exists, the existing label will be returned. Both new and existing labels return the same object structure; check the label's `createdAt` or compare IDs to determine if creation occurred. | | `LINEAR_CREATE_LINEAR_PROJECT` | Create Project | Creates a new Linear project with specified name and team associations. | | `LINEAR_CREATE_PROJECT_MILESTONE` | Create Project Milestone | Tool to create a project milestone in Linear with a name and optional target date and sort order. Use when you need to add milestones to track progress within a project. | | `LINEAR_CREATE_PROJECT_UPDATE` | Create Project Update | Tool to create a project status update post for a Linear project. Use when you need to post progress updates, status reports, or announcements for a project. | | `LINEAR_DELETE_LINEAR_ISSUE` | Delete issue | Archives an existing Linear issue by its ID, which is Linear's standard way of deleting issues; the operation is idempotent. Archiving is permanent with no built-in undo — confirm the issue identifier and title with the user before executing, especially in bulk operations. | | `LINEAR_GET_ATTACHMENT` | Download issue attachments | Downloads a specific attachment from a Linear issue; the `file_name` must include the correct file extension. | | `LINEAR_GET_CURRENT_USER` | Get current user | Gets the currently authenticated user's ID, name, email, and other profile information — this is the account behind the API token, which may be a bot or service account rather than a human user. Use the returned `id` field (nested under `data.viewer`) for downstream Linear operations requiring user ID filtering. To search or compare other workspace members, use LINEAR_LIST_LINEAR_USERS instead. | | `LINEAR_GET_CYCLES_BY_TEAM_ID` | Get cycles by team ID | Retrieves all cycles for a specified Linear team ID; cycles are time-boxed work periods (like sprints). Results are team-scoped to the given team_id. To identify the active cycle, check that the current date (in UTC) falls between a cycle's startAt and endAt fields; either field may be null. Results may be paginated — follow page_info cursors to retrieve all cycles. | | `LINEAR_CREATE_LINEAR_ISSUE_DETAILS` | Get create issue default params | Fetches a Linear team's default issue estimate and state, useful for pre-filling new issue forms. | | `LINEAR_GET_LINEAR_ISSUE` | Get Linear issue | Retrieves an existing Linear issue's comprehensive details, including id, identifier, title, description, timestamps, state, team, creator, attachments, comments (with user info and timestamps, use issue.comments.nodes for comment IDs), subscribers, and due date. Does not include parent, milestone, cycle, or relation graphs—use LINEAR_RUN_QUERY_OR_MUTATION for those. Optional fields (labels, project, state, assignee, cycle) may be null; guard against null when accessing nested properties. Returns null or 'Entity not found' for invalid IDs, cross-workspace IDs, or restricted teams. Rate limit: ~60 req/min; HTTP 429 on excess—apply exponential backoff and respect Retry-After headers. | | `LINEAR_GET_LINEAR_PROJECT` | Get Linear project | Retrieves a single Linear project by its unique identifier. Use when verifying a newly created or updated project, or when fetching detailed project information by ID. | | `LINEAR_LIST_ISSUE_DRAFTS` | List issue drafts | Tool to list issue drafts. Use when you need to fetch draft issues for review or further editing. Check `pageInfo.hasNextPage` in the response to determine if additional drafts exist beyond the current page. | | `LINEAR_LIST_ISSUES_BY_TEAM_ID` | List issues by team ID | Tool to list all issues for a specific Linear team, scoped by team ID. Use when you need to retrieve issues belonging to a particular team without fetching workspace-wide issues. This is more efficient than workspace-wide listing followed by client-side filtering. | | `LINEAR_LIST_LINEAR_CYCLES` | Get all cycles | Retrieves all cycles (time-boxed sprint iterations) org-wide from the Linear account; no filters applied. In large multi-team workspaces this produces heavy responses — filter client-side by team ID and date range using each cycle's startsAt/endsAt fields. Cycles are team-scoped; always group by team ID to avoid mixing sprints across teams. To identify the active sprint, verify the current UTC timestamp falls between startsAt and endsAt, and handle null startsAt/endsAt defensively. Timestamps are UTC. Results may be paginated; follow pageInfo.endCursor and hasNextPage until hasNextPage is false to avoid truncated lists. | | `LINEAR_LIST_LINEAR_ISSUES` | List Linear issues | Lists non-archived Linear issues; if project_id is not specified, issues from all accessible projects are returned. Can filter by assignee_id. Only project_id and assignee_id server-side filters are supported; label, state, team, cycle, or date filters must be done client-side or via LINEAR_RUN_QUERY_OR_MUTATION. Response is a flat issues array plus page_info object (not GraphQL nodes/pageInfo). Fields like cycle membership, dueDate, completedAt, comments, and attachments are absent; use LINEAR_GET_LINEAR_ISSUE for enrichment. state and labels are nested objects (labels as labels.nodes array). Response order is not guaranteed; sort client-side after collecting all pages. No team_id filter; scope by project_id or use LINEAR_RUN_QUERY_OR_MUTATION. | | `LINEAR_LIST_LINEAR_LABELS` | Get labels | Retrieves labels from Linear. If team_id is provided, returns labels for that specific team; if omitted, returns all labels across the workspace. Label names are not unique across teams — always use returned IDs, not names, and track each label ID with its team ID. In large workspaces, results may paginate; follow pageInfo.hasNextPage and pageInfo.endCursor to retrieve all labels. | | `LINEAR_LIST_LINEAR_PROJECTS` | List linear projects | Retrieves all projects from the Linear account. Returns a flat array (not a GraphQL connection) with fields id and name; use LINEAR_RUN_QUERY_OR_MUTATION for progress, state, issues, or team linkage. No server-side filtering: all workspace projects are returned regardless of team or name — filter client-side. Multiple projects can share identical names; always confirm project_id before downstream use. Results are permission-scoped to the connected user. Pagination: loop while page_info.hasNextPage is true, passing page_info.endCursor as after, or results will be silently truncated. HTTP 429 may occur in large workspaces; apply exponential backoff between calls. | | `LINEAR_LIST_LINEAR_STATES` | List Linear states | Retrieves all workflow states for a specified team in Linear, representing the stages an issue progresses through in that team's workflow. Returned state IDs are team-scoped — never reuse a stateId across different teams, as this causes validation errors or 'Entity not found' failures in tools like LINEAR_UPDATE_ISSUE. State names (e.g., 'Done', 'In Progress') are non-unique across teams; always resolve names to IDs via this tool for the specific team_id before using them in filters or mutations. Uses cursor-based pagination via pageInfo.hasNextPage and endCursor; iterate until hasNextPage is false to avoid missing states in large workspaces. Always fetch fresh state IDs rather than hardcoding or reusing stale values. | | `LINEAR_LIST_LINEAR_TEAMS` | Get teams | Retrieves all teams with their members and projects. Use stable team IDs or keys (not display names) for subsequent operations — names are non-unique. Results reflect only teams visible to the authenticated token scope; missing teams or members indicate permission limits. Large workspaces paginate via pageInfo.hasNextPage/endCursor — incomplete pagination silently drops teams or members. Members may belong to multiple teams; deduplicate user IDs when aggregating. Use LINEAR_GET_ALL_LINEAR_TEAMS instead when only identifiers are needed. | | `LINEAR_LIST_LINEAR_USERS` | List Linear users | Lists all workspace users (not team-scoped) with their IDs, names, emails, and active status. Display names are non-unique — use email to disambiguate before extracting an ID. Only assign users with `active: true`. Returned IDs are UUID strings; pass them as-is to fields like `assignee_id` — never substitute names, emails, or tokens. When joining with other tools, always join on IDs. | | `LINEAR_REMOVE_ISSUE_LABEL` | Remove label from Linear issue | Removes a specified label from an existing Linear issue using their IDs; successful even if the label isn't on the issue. Operation is irreversible — obtain explicit user approval before executing. Use this tool instead of LINEAR_UPDATE_ISSUE to avoid replacing the entire label set. | | `LINEAR_REMOVE_REACTION` | Remove reaction from comment | Tool to remove a reaction on a comment. Use when you have a reaction ID and need to delete it. | | `LINEAR_RUN_QUERY_OR_MUTATION` | Run Query or Mutation | Execute any GraphQL query or mutation against Linear's API. USE WHEN: No dedicated action exists, need complex filtering, custom fields, or schema discovery. *** INTROSPECTION FIRST - NEVER GUESS FIELD NAMES *** Run introspection before unknown operations: - query { __type(name: "Issue") { fields { name } } } - query { __type(name: "Mutation") { fields { name } } } Linear uses nested objects (project { id }), NOT scalar IDs (projectId). KEY: All IDs are UUIDs. Filter: { field: { eq: value } }. Pagination: nodes[] + pageInfo. | | `LINEAR_SEARCH_ISSUES` | Search Linear issues | Search Linear issues using full-text search across identifier, title, and description. Use when you need to find issues by keywords or specific identifiers. Note: This endpoint only supports full-text search; for structured filtering by team, project, assignee, state, or labels, use LIST_ISSUES_BY_TEAM_ID instead. | | `LINEAR_UPDATE_ISSUE` | Update issue | Updates an existing Linear issue using its `issue_id`; requires at least one other attribute for modification, and all provided entity IDs (for state, assignee, labels, etc.) must be valid UUIDs — only `issueId` accepts key format (e.g., 'ENG-123'). All updated fields are fully overwritten, not merged; omit any field you do not intend to change. | | `LINEAR_UPDATE_LINEAR_COMMENT` | Update a comment | Tool to update an existing Linear comment's body text. Use when you need to edit or modify the content of a previously created comment. | | `LINEAR_UPDATE_LINEAR_PROJECT` | Update Project | Tool to update an existing Linear project. Use when you need to modify project properties like name, description, state, dates, or lead. All fields except project_id are optional - only provide the fields you want to update. | ## Supported Triggers | Trigger slug | Name | Description | |---|---|---| | `LINEAR_COMMENT_EVENT_TRIGGER` | Comment Received Trigger | Triggered when a comment is received. | | `LINEAR_ISSUE_CREATED_TRIGGER` | Issue Created Trigger | Triggered when a new issue is created. | | `LINEAR_ISSUE_UPDATED_TRIGGER` | Issue Updated Trigger | Triggered when an issue is updated. For example labels are changed, issue status is changed, etc. | ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Antigravity can access the Linear MCP server via Composio to run actions that you authorize directly from the agent panel. ## Complete Code None listed. ## Conclusion ### Conclusion You have successfully connected Linear to Antigravity using Composio Connect.

With a standalone Linear MCP server, the agents and LLMs can only access a fixed set of Linear tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Linear and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Antigravity? Yes, you can. Antigravity fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Linear tools. ### Can I manage the permissions and scopes for Linear while using Tool Router? Yes, absolutely. You can configure which Linear scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Linear data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
