How to add PostHog MCP
Prepare a PostHog connection and understand the setup requirements before adding its Durin URL to an agent.
Check the supported setup path
The PostHog library profile uses https://mcp.posthog.com/mcp?mode=cli&readonly=true for CLI mode and read-only discovery. The current Custom MCP form rejects query strings, while the named provider card does not supply this endpoint. This profile needs deployment work before self-service setup can finish.
Save or request the installation
Name the connection for the intended provider workspace so it can be distinguished from other installations.
- As an administrator, open Connections → All providers and choose PostHog.
- Choose User signs in and OAuth, enter registered client details if your deployment owner supplies them, then save the draft.
- As a member, request the provider from Available connections instead. An approved request still requires setup.
Continue after runtime support is available
Follow Add a provider connection: complete provider consent, discover tools, save permission review, obtain its validator release, run a reviewed read test and accept the activation preview. Keep the connection disabled until every checkpoint passes.
After activation, complete personal provider access and copy the connection URL. Follow MCP client setup to authenticate your agent and verify the reviewed read.
Troubleshooting
Can I remove the endpoint query parameters?
No. CLI mode and readonly=true define the selected read-only profile. Ask the deployment owner for reviewed support for that exact endpoint.
Frequently asked questions
Does the provider adapter activate this connection?
No. Library fixtures do not establish live provider acceptance or implement the missing setup path.
