This guide explains the easiest and most robust way to connect your PostHog account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either. ## Also integrate PostHog MCP with - [ChatGPT](https://composio.dev/toolkits/posthog_mcp/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/posthog_mcp/framework/claude-cowork) ## TL;DR ### What is Composio Connect? Composio Connect is a consumer offering that lets anyone plug 1,500+ applications directly into their agent harness — including Hermes. It can: - Search and load tools from relevant toolkits on-demand, reducing context usage. - Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM. - Manage app authentication end-to-end with zero manual overhead. ## Connect PostHog MCP to Hermes ### Integrating PostHog with Hermes ### Using Composio Connect CLI 1. Install the Composio CLI Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you. ```bash curl -fsSL https://composio.dev/install | bash ``` ## What is the PostHog MCP server, and what's possible with it? The PostHog MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your PostHog account. It provides structured and secure access so your agent can perform PostHog operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `POSTHOG_MCP_EXEC` | Exec | ### Using the `posthog` tool PostHog makes your product self-driving: it reads your data and ships changes with you, never without you. Spans analytics, experiments, flags, replay, and more. Pass CLI-style commands in the `command` parameter for all PostHog interactions. **Requirements** 1. Find unknown tools with `search` or `tools`. 2. Run `info ` once if its schema is not in context. Reuse it unless the tool changes or a schema error occurs. Never guess a schema or run `info` before every call. **Commands (in order):** ```text # 1. Find unknown tools posthog:exec({ "command": "search " }) posthog:exec({ "command": "tools" }) # fallback: list all # 2. Inspect once if the schema is missing posthog:exec({ "command": "info " }) # 3. Drill into complex fields — REQUIRED for any field with a `hint` posthog:exec({ "command": "schema " }) # 4. Call; reuse the schema posthog:exec({ "command": "call " }) posthog:exec({ "command": "call --json " }) ``` **Schema drill-down:** - `info` returns the full schema if it fits the token budget; otherwise it auto-summarizes (names, types, required, enums, defaults) and attaches `hint` entries pointing to `schema ` for complex fields. - `schema ` (no path) returns the summarized top-level schema. - `schema ` resolves a dot path, descending through: - object `properties` (e.g. `query.source`) - array `items` — numeric segments step into items (`events.0.properties`), or jump to a property on the item type (`events.id`) - `anyOf`/`oneOf` — numeric segment picks a variant by index, or a property name matches any object variant defining it - Oversized sub-schemas are also summarized with a `note` to drill further. - Unknown paths return an error listing available child paths. **Not supported:** - `search` matches tool metadata only, not input schemas. - No pattern-based field projection — drill one path at a time. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The PostHog MCP server provides comprehensive access to PostHog operations through Composio. Once connected, Hermes can perform all major PostHog actions on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With PostHog connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to. From here, you can extend Hermes further: - Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you. - Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft. - Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

With a standalone PostHog MCP server, the agents and LLMs can only access a fixed set of PostHog tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from PostHog and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Hermes? Yes, you can. Hermes 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 PostHog tools. ### Can I manage the permissions and scopes for PostHog while using Tool Router? Yes, absolutely. You can configure which PostHog 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 PostHog data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
