## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like Attio through MCP without you sharing account credentials directly with the agent.

## What is the Attio MCP server, and what's possible with it?

The Attio MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Attio account. It provides structured and secure access to your team’s relationship and workflow data, so your agent can perform actions like creating records, managing notes, searching your CRM, and organizing lists on your behalf.
- Automated record management: Effortlessly create, update, or permanently delete records for people, companies, deals, and more in your Attio workspace.
- Smart note taking and retrieval: Let your agent create, list, or delete notes attached to any record, keeping important context and meeting details organized for your team.
- Powerful object and list navigation: Retrieve and explore all available objects or lists within your workspace, making it easy for your AI to understand and organize your CRM structure.
- Advanced record search and filtering: Find specific CRM records either by unique ID or by searching with custom attributes, ensuring your agent surfaces the right data when you need it.
- Comprehensive workspace insight: Get detailed information about object types and their attributes, so your AI-powered workflows always use the right fields and relationships.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ATTIO_ASSERT_COMPANY` | Assert Company (Create or Update) | Creates or updates a company record in Attio using a unique attribute to search for existing companies. If a company is found with the same value for the matching attribute, that company will be updated. If no company is found, a new one will be created. Use this when you prefer to update records on conflicts. |
| `ATTIO_ASSERT_PERSON` | Assert Person Record | Tool to create or update person records using a unique attribute to search for existing people. Use when you want to ensure a person exists with specific details without creating duplicates. |
| `ATTIO_ASSERT_USER_RECORD` | Assert User Record (Create or Update) | Creates or updates a user record in Attio using a unique attribute to search for existing users. If a user is found with the same value for the matching attribute, that user will be updated. If no user is found, a new one will be created. Use this to ensure user records exist without duplicates. |
| `ATTIO_ASSERT_WORKSPACE` | Assert Workspace (Create or Update) | Creates or updates a workspace record in Attio using a unique attribute to search for existing workspaces. If a workspace is found with the same value for the matching attribute, that workspace will be updated. If no workspace is found, a new one will be created. |
| `ATTIO_CREATE_ATTRIBUTE` | Create Attribute | Tool to create a new attribute on an object or list in Attio. Use when you need to add custom fields to track additional information. For record-reference types, you can establish bidirectional relationships by supplying a relationship object. |
| `ATTIO_CREATE_COMMENT` | Create Comment | Tool to create a new comment on a thread, record, or list entry in Attio. Use when you need to add a comment to an existing conversation, a record (like a person, company, or deal), or a list entry. |
| `ATTIO_CREATE_COMPANY` | Create Company | Creates a new company record in Attio. This endpoint will throw an error on conflicts of unique attributes like domains. If you prefer to update company records on conflicts, use the Assert company record endpoint instead. Note: The logo_url attribute cannot currently be set via the API. |
| `ATTIO_CREATE_DEAL_RECORD` | Create Deal Record | Tool to create a new deal record in Attio. Use when you need to track a new sales opportunity or deal. This endpoint will throw an error on conflicts of unique attributes. Minimal requirement is providing at least one attribute value. |
| `ATTIO_CREATE_LIST` | Create List | Tool to create a new list in Attio. Use when you need to organize records into custom lists. Once created, add attributes using the Create Attribute API and add records using the Create Entry API. New lists must have either workspace_access set to 'full-access' or one or more workspace_member_access with 'full-access' level. |
| `ATTIO_CREATE_NOTE` | Create Note | This tool creates a new note on a given record in Attio. The note can be attached to any record type (like person, company, or deal) and includes a title and content. It requires parameters such as parent_object, parent_record_id, title, and content, with an optional created_at timestamp. |
| `ATTIO_CREATE_OBJECT` | Create Object | Tool to create a new custom object in your Attio workspace. Use when you need to add a new object type beyond the standard objects (people, companies, deals, users, workspaces). Requires api_slug (snake_case identifier), singular_noun, and plural_noun. |
| `ATTIO_CREATE_PERSON` | Create Person | Creates a new person record in Attio. This endpoint will throw an error on conflicts of unique attributes like email_addresses. If you prefer to update person records on conflicts instead, use the Assert person record endpoint. Note: The avatar_url attribute cannot currently be set via the API. |
| `ATTIO_CREATE_RECORD` | Create Record | This tool creates a new record in Attio for a specified object type (people, companies, deals, users, workspaces, etc.). It requires the object type and a values dictionary containing the attributes for the new record. IMPORTANT: Different object types have different attributes. For example: - 'people' object uses: name, email_addresses, phone_numbers, primary_location, job_title, etc. - 'users' object uses: primary_email_address, user_id, person, workspace - 'companies' object uses: name, domains, description, etc. Always verify the correct attribute names for your target object type before creating records. Use the List Attributes API or check your workspace to see available attributes for each object type. |

Also use as a prerequisite validation step before calling ATTIO_FIND_RECORD, ATTIO_LIST_RECORDS, or ATTIO_CREATE_RECORD — attribute slugs must exactly match what this tool returns. The returned schema defines required attributes for record creation; omitting them causes invalid_request_error with code missing_value (HTTP 400). Custom attributes (e.g., industry, category) vary by object type — verify their presence and data type here before building filters or record values. |
| `ATTIO_GET_RECORD_ENTRIES` | List Record Entries | Tool to list all entries, across all lists, for which a record is the parent. Use when you need to find which lists a specific record belongs to. Returns list IDs, slugs, entry IDs, and creation timestamps. |

| `ATTIO_LIST_LISTS` | List Lists | This tool retrieves all lists available in the Attio workspace, sorted as they appear in the sidebar. Returns list metadata only (names, IDs, configuration) — not the records/entries within those lists. To fetch actual list entries, use ATTIO_FIND_RECORD with appropriate filters. This tool is a prerequisite for many list-related operations. Requires the list_configuration:read permission scope. |
| `ATTIO_LIST_MEETINGS` | List Meetings | Tool to list all meetings in the workspace using a deterministic sort order. Use when you need to retrieve meetings, optionally filtering by participants, linked records, or time ranges. This endpoint is in beta. |
| `ATTIO_LIST_NOTES` | List Notes | Lists notes in Attio. Can list all notes in the workspace, or filter by parent object type and/or specific record. Notes are returned in reverse chronological order (newest first). |
| `ATTIO_LIST_OBJECTS` | List Objects | This tool retrieves a list of all available objects (both system-defined and user-defined) in the Attio workspace via GET /v2/objects, returning key metadata including slugs and IDs for each object. Call this tool first before ATTIO_LIST_RECORDS, ATTIO_FIND_RECORD, or ATTIO_CREATE_RECORD to discover valid object slugs — hardcoded slugs may not exist across workspaces. Concepts like tasks may be modeled as deals or custom objects rather than dedicated types, so confirm the correct object type before proceeding. Attribute values in responses can be arrays of time-bounded entries rather than simple scalars; downstream code must handle nested structures. |
| `ATTIO_LIST_PEOPLE_ATTRIBUTE_VALUES` | List People Attribute Values | Tool to get all values for a given attribute on a person record.

Use when you need to see which lists a particular person record belongs to. Returns list information and entry IDs for each list the person appears in. |
| `ATTIO_LIST_RECORD_ATTRIBUTE_VALUES` | List Record Attribute Values | Tool to retrieve all values for a specified attribute on a record in Attio. Use when you need to see the history of values for a specific attribute. Can return only active values or include historical values. Historic values cannot be queried on COMINT or enriched attributes. |
| `ATTIO_LIST_RECORDS` | List Records | This tool lists records from a specific object type in Attio. It provides simple pagination support and returns records in creation order (oldest first). For complex filtering, use the FindRecord action instead. Standard object types include: people, companies, deals, users, workspaces. If you get a 404 error, verify the object type exists using the List Objects action first. Response attribute values are returned as arrays of time-bounded objects under a `values` map (e.g., `values['name']`), not simple scalars — handle arrays, nested objects, and empty arrays accordingly. Select attributes are accessed via `option.title`; currency, stage, and select fields may be null or empty arrays. Access records via `data.data` in the response. |
| `ATTIO_LIST_THREADS` | List Threads | Tool to list threads of comments on a record or list entry in Attio. Use when you need to view all comment threads associated with a specific record or list entry. Threads contain one or more comments sorted chronologically. |
| `ATTIO_LIST_USER_RECORD_ENTRIES` | List User Record Entries | Tool to list all entries across all lists for which a user record is the parent in Attio. Use when you need to see which lists a particular user record belongs to. Returns list information and entry IDs for each list the user appears in. |

| `ATTIO_LIST_WORKSPACE_MEMBERS` | List Workspace Members | Tool to list workspace members (actors) so agents can reliably assign owners and resolve workspace-member IDs even when the optional Users standard object is disabled. Use when writing or assigning actor-reference attributes (e.g., record/list entry owners) that require referenced_actor_type=workspace-member and an actor id. |
| `ATTIO_LIST_WORKSPACE_RECORD_ATTRIBUTE_VALUES` | List Workspace Record Attribute Values | Tool to retrieve all values for a specified attribute on a workspace record in Attio. Use when you need to see the history of values for a specific attribute on a workspace record. Can return only active values or include all historical values sorted chronologically. |
| `ATTIO_LIST_WORKSPACE_RECORD_ENTRIES` | List Workspace Record Entries | Tool to list all entries across all lists for which a workspace record is the parent in Attio. Use when you need to see which lists a particular workspace record belongs to. Returns list information and entry IDs for each list the workspace appears in. |
| `ATTIO_LIST_WORKSPACE_RECORDS` | List Workspace Records | Tool to list workspace records with filtering and sorting options. Use when you need to retrieve workspace-level records from Attio. Records are returned based on the filters and sorts provided. Requires record_permission:read and object_configuration:read scopes. |

Use the PATCH endpoint to add multiselect attribute values without removing those that already exist. |
| `ATTIO_PUT_V2_OBJECTS_OBJECT_RECORDS` | Assert Record (Create or Update) | Tool to create or update people, companies and other records in Attio using a matching attribute. Use when you want to avoid duplicate records - if a record with the same value for the matching attribute is found, it will be updated; otherwise a new record is created. If you want to avoid matching and always create new records, use the Create Record endpoint instead. |
| `ATTIO_PUT_V2_OBJECTS_OBJECT_RECORDS_RECORD_ID` | Put Record (Overwrite) | Tool to update people, companies, and other records by record_id using PUT method. For multiselect attributes, values supplied will overwrite/remove existing values. Use PATCH endpoint to append without removing. |

Use when you need to retrieve records based on complex filter criteria (e.g., 'get all agreements where product=X and status in Y') rather than simple listing or ID-based lookup. This avoids downloading large pages and filtering locally, which is slow and costly. |
| `ATTIO_SEARCH_RECORDS` | Search Records | Tool to fuzzy search for records across multiple objects in Attio. Use when you need to find records by name, domain, email, phone number, or social handle. This endpoint is in beta and returns eventually consistent results.

| `ATTIO_UPDATE_LIST` | Update List | Tool to update an existing list in Attio. Use when you need to modify list properties like name, api_slug, or permissions. Lists must have either workspace_access set to 'full-access' or one or more workspace_member_access with 'full-access' level. Changing the parent object of a list is not possible through the API. |
| `ATTIO_UPDATE_OBJECT` | Update Object | Tool to update a single object's configuration in Attio. Use when you need to modify an object's API slug, singular noun, or plural noun. Standard objects (people, companies, deals, users, workspaces) and custom objects can be updated. |
| `ATTIO_UPDATE_PERSON` | Update Person | Tool to update a person record in Attio by its record_id. Use when you need to modify person attributes like name, email, job title, or phone numbers. For multiselect attributes, values are prepended to existing values. Note: avatar_url cannot be updated via API. |
| `ATTIO_UPDATE_RECORD` | Update Record | This tool updates an existing record in Attio for a specified object type (people, companies, deals, users, workspaces, etc.). It uses PATCH to partially update only the provided fields, leaving other fields unchanged. |
| `ATTIO_UPDATE_SELECT_OPTION` | Update Select Option | Tool to update an existing select option for a select or multiselect attribute in Attio. Use when you need to rename an option or archive it. Archived options are hidden from selection but preserve historical data for records that used them. |
| `ATTIO_UPDATE_STATUS` | Update Status | Tool to update a status on a status attribute on either an object or a list in Attio.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Attio MCP?

With a standalone Attio MCP server, the agents and LLMs can only access a fixed set of Attio tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Attio and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork 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 Attio tools.

### Can I manage the permissions and scopes for Attio while using Tool Router?

Yes, absolutely. You can configure which Attio 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 Attio data and credentials are handled as safely as possible.
