The authoritative reference for adding a NEW external MCP server to Tlamatini universal MCP client layer. Covers the full lifecycle: catalog import, transport selection, activation, runtime provisioning, diagnosis, verification, and troubleshooting. READ THIS BEFORE calling external_mcp_import, before editing external_mcps.json, or before activating a new server.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Adding External MCP — canonical reference > Current release: **[v1.91.1](../../../../docs/changes/2026-10-27-v1.91.1.md)**. Dated records below retain their original evidence dates. > **HEADLESS IS FORBIDDEN. VISIBLE FOREGROUND EXECUTION ONLY.** Every command, automated test, diagnostic, script, build, agent and browser must run in a visible foreground window on Angela's real desktop. Use forked CMD/PowerShell windows, `execute_forked_window: true`, and `headless: false`. Monitor live; if visibility cannot be confirmed, do not run. Read the [mandatory execution policy](../../../../TestsVisiblesAndVisibleExecutionFromClaude2Codex.md). The full, ground-truth procedure for adding a NEW external MCP server to Tlamatini universal MCP client layer. This skill makes Tlamatini autonomously capable of adding, configuring, activating, and verifying any external MCP server — robustly and bullet-proof. ## What this skill does Enables Tlamatini to add ANY external MCP server to her universal MCP client layer — the system that lets her use tools from arbitrary MCP servers declared in a JSON catalog (external_mcps.json), with no code per server. ## Architecture overview ``` …

How to install
mdr add xaiht/tlamatini/adding-external-mcp@sha256:953e948c1ec0cfb0The line at the top of this page pins the label git:20261027.1d13922, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
