Flowlines plugins

Official Flowlines plugins for MCP observability. This repository ships the portable flowlines plugin, marketplaces for Claude Code and Codex, and a Cursor plugin manifest (plugins/flowlines/.cursor-plugin/plugin.json) for cursor.directory:

Privacy notice

• The Flowlines MCP server reads production MCP sessions, tool calls, and user activity. Treat everything it returns as confidential; it never writes to your namespace except through the explicit save_note and report_outcome tools.
• An MCP server instrumented from the onboarding plan exports validated tool arguments, client-visible results, and user identity metadata to Flowlines. That data can contain personal data, customer data, source code, or other sensitive content. You choose what it records on the Flowlines get-started page.
• reason and user_intent are short sentences that the calling model writes, and they do not need to identify anyone. If your privacy rules do not allow user_intent, keep it and remove the identity instead: send no user.name or user.email, and send an HMAC-SHA-256 of your user ID as user.id. The hash stays the same for one user, so Flowlines still groups the calls into sessions. Without user_intent, only clients that send a session ID get sessions.

onboarding and check_onboarding are read-only: they return an instrumentation plan and check the calls that arrive. The namespace API key is created on the Flowlines get-started page and shown once there; never paste it into chat.

Install

ChatGPT and Codex public plugin

The public distribution target is one Flowlines plugin with the hosted MCP server and four shared analysis skills in OpenAI's Plugins Directory. This repository prepares its submission; merging changes does not publish it or install it for users. A public listing and installation reuse across products still require review and verification.

See the shared plugin guide for the build and verification steps, and the submission worksheet for listing assets and review cases. The existing desktop marketplace installs below continue to work. Personal ChatGPT accounts can test the server separately through Developer mode while the public submission is being prepared.

Claude Code

claude plugin marketplace add flowlines-ai/plugins && claude plugin install flowlines@flowlines

Then run /mcp inside Claude Code and sign in to flowlines. Skills are available as /flowlines:<skill-name>, for example /flowlines:flowlines-weekly-review or /flowlines:flowlines-doctor. Add --scope project to the install command to enable the plugin for one repository only.
