## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agents receive governed app tools through the MCP gateway. > - GitHub review tasks can contain a PR discussion and inline finding threads. > - Discovery repeated each tool for every conversation linked to the task. > - Native tool registration treated these repeated descriptors as a fatal collision. > - This pull request lists GitHub tools once and deduplicates identical descriptors across providers. > - Agents can continue work while conflicting definitions and normal tool permissions remain enforced. ## Linked Issues or Issue Description **What happened?** A follow-up run on a GitHub review task failed with `assigned_mcp_tool_name_collision` before the provider started. The task had a main conversation and an inline finding thread. Discovery returned the same seven tools twice. Repeated descriptors from other providers could cause the same failure. **Expected behavior** Discovery exposes each identical tool once. Separate connection names remain separate tools. Conflicting definitions remain an error. Every call still passes the gateway's policy, approval, revocation, and audit checks. **Steps to reproduce** 1. Run a GitHub review and publish an inline finding. 2. Send a follow-up request on the same PR task. 3. Inspect the task-bound bot catalog and the next native startup. 4. Separately, return two identical descriptors from an assigned app or plugin catalog. Related: #13717 added the GitHub review workflow. ## What Changed - Use a distinct GitHub discovery query across conversations that share an endpoint and task. Keep both thread mappings. - Deduplicate identical gateway descriptors by their full gateway name across providers. Use this rule for MCP listings, plugin listings, assigned-tool startup, and fresh assigned-tool discovery. - Reject conflicting descriptors with `tool_name_collision`. Keep the projected-name collision guard. - Cover GitHub inline-thread discovery, repeated plugin/app tools, direct and on-demand catalogs, revocation, conflicting bindings, and separate connection names. - Update the execution contract, GitHub documentation, and agent access map. ## Verification - Regression baseline: six new assertions failed on the original implementation. GitHub returned fourteen entries, plugin discovery repeated a tool, and native startup failed on repeated app tools. - Focused verification passed: 272 GitHub cases, all 29 assigned-tool cases, and all 88 gateway acceptance cases. - `pnpm -r typecheck` passed. - `pnpm build` passed. - `node scripts/check-maps.mjs` passed. - Current-head CI passed: 55 checks passed, two inapplicable checks skipped. Greptile scored the current head 5/5 with no unresolved threads. - Full local `pnpm test:run` encountered a 15-second timeout in the existing bearer-auth throttling test, before tool discovery. That test passed in the separate 88-case gateway run and on one isolated rerun. The duplicate broad local run was then stopped; the complete current-head CI matrix passed. ## Risks - Deduplication keeps the first identical descriptor and preserves listing order. Same-name descriptors with different definitions fail with HTTP 409 rather than selecting an ambiguous binding. - The GitHub query changes result cardinality. It retains the existing task/company/agent filters and leaves conversation rows intact. - No schema migration or credential change. Live staging recovery requires deployment and a new authorized run. ## Model Used OpenAI Codex, based on GPT-6, with code inspection, editing, browser investigation, and test execution.
