## Thinking Path > - Paperclip manages agents and their access to external tools. > - Connectors expose these tools through a governed MCP gateway. > - PR #13755 added a direct Composio MCP connection behind the experimental MCP aggregators flag. > - The old project API-key broker still created toolkit child connections and showed a separate Services tab. > - Keeping both paths leaves obsolete setup and session code in the product. > - This change removes the broker and preserves direct MCP setup, credentials, permissions, and execution. > - Saved legacy records fail closed and remain available for explicit removal. ## Linked Issues or Issue Description Related: #13755. This retirement supersedes the legacy-path fixes proposed in #12630, #12632, #12634, and #12906. It does not close those PRs. **What existing behavior does this improve?** Composio connector setup, management, and runtime dispatch. **Current behavior** Composio offers both direct MCP and a project API-key broker. The broker mints sessions and creates one child connection per toolkit. **Proposed behavior** Offer only direct MCP. Remove the toolkit Services UI, REST routes, API client, and session broker. Block saved legacy parent and child records from discovery, execution, health checks, reconnect, and OAuth. Preserve their records and credentials until the operator removes each connection. **Reason and benefit** The direct MCP connector becomes the single supported Composio workflow. Provider accounts remain managed in Composio. ## What Changed - Remove the API-key catalog method and its generated-source definition. - Delete Composio broker clients, session creation, account synchronization, child lifecycle, and toolkit routes. - Remove the Services tab, service rows, child provenance, and cascade-removal controls. Keep Vercel provenance intact. - Retain a shared retirement guard for stored legacy records. Show Retired status and replacement/removal guidance in the connection list and details; hide obsolete runtime controls. - Preserve the experimental MCP aggregators flag and direct MCP infrastructure. - Replace broker fixtures with retirement tests and extend direct Composio catalog/reconnect coverage. ## Verification - Focused shared, server, and UI tests passed with one worker. Server retirement tests use a name filter; no full local test suite was run, as requested. - Server and UI TypeScript checks passed. - Token gates and UI build passed. - Real browser: opened the saved Composio connection, refreshed all 11 tools, and ran the provider's read-only GitHub account-list operation through the standard Test dialog as an agent. The provider returned success using the existing OAuth credentials. - See `doc/connections/COMPOSIO-BROKER-RETIREMENT.md` for scope and live evidence. - Storybook build passed. A fresh real agent used `COMPOSIO_SEARCH_TOOLS` and `COMPOSIO_MULTI_EXECUTE_TOOL` to return the actual Paperclip DeepWiki hierarchy: one success, zero errors. Gateway audit records confirm both calls succeeded. - Browser retirement check: a credential-free legacy fixture showed the guidance, opened the direct MCP replacement flow, and was removed through the standard confirmation. - Focused regressions for the experimental settings copy and exact OpenAPI route coverage passed. All latest-head CI checks passed (54 successful, two intentionally skipped); Greptile scored 5/5 with no unresolved review threads. The PR has no merge conflicts. ## Risks This intentionally breaks the old Composio project API-key and child-connection workflow. Existing legacy records cannot run, even if their stored status is active. Operators must create a new direct MCP connection and choose access rules; credentials and grants are not migrated. Remove each old record separately to delete its credentials. No schema migration or data deletion runs automatically. Direct MCP connections keep their existing grants and secrets. ## Model Used OpenAI GPT-6 via Codex, with reasoning, code execution, and browser tools. The exact runtime variant and context-window size are not exposed in this session. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
