mcp-server: Instructions file for Codex

AGENTS.md

mcp-server AGENTS.md is an instructions file for Codex, OpenCode from itmplatform/mcp-server. It costs 1,022 tokens per session, scanned A, original, MIT.

Repository instructions for an AI coding agent working on the ITM.MCP server. They list which documentation to read first and which commands start, build, and test the project.

In plain words
What is it for?
Following startup instructions, running the development server, building the project, and running unit or end-to-end tests.
Why use it?
They prevent the agent from missing shared project rules, important documentation, or required checks before changing code.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is itmplatform/mcp-server's own configuration. It tells Codex and OpenCode how to work on mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-server AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ITM.MCP agent instructions

Required startup

Before investigating, planning, or changing anything:

  1. Read ../AGENTS.md. Its engineering, documentation, testing, security, Git, and deployment rules are mandatory here.
  2. Read ../README.md for platform-wide context and documentation routing.
  3. Read this repository's README.md.
  4. Read ../test-and-build.md before building or testing.
  5. Read the active specification and zz_Specifications/INDEX.md when a task changes a documented MCP contract.

Only this repository's root README is mandatory. Nested READMEs are contextual and should only be read when the task directly concerns their directory.

Before concluding that server, database, Help Scout, logging, or other access information is unavailable, follow the documentation routing in ../AGENTS.md and ../README.md.

  • This repository owns the MCP server, tool and resource schemas, OAuth and API-key transports, REST and DataMart routing, server-side audit behavior, the npm package, and MCP public API documentation.
  • ITM.Tasks and other platform APIs own canonical write and single-record behavior. ITM.DataMart owns analytical reads, ITM.Web owns API gateway and OAuth integration, and ITM.Connector owns the DataMart extension lifecycle.
  • Treat required changes in sibling repositories as separate work in their own Git roots. Keep API gateway routes, REST contracts, DataMart fields, permissions, tool schemas, tests, and published documentation aligned across all affected sides.

DataMart activation and regeneration

  • Current ITM.Connector behavior keeps onEnabled cheap and idempotent on every active save. Expensive DataMart backfill is in onActivated, which runs only on an inactive-to-active transition.
  • Activating a tenant still schedules a full tenant regeneration. Never perform bulk production activation or regeneration during business hours. Use approved off-peak batches and the DataMart /regenerate or /regenerate-many endpoints when explicit regeneration is required.
  • During a staged rollout, verify the exact deployed ITM.Connector revision and extension template before relying on this split. Older deployments fired regeneration from onEnabled on every active save.
  • The incident evidence and historical mechanism are in ../zz_Tickets/2026-08-07-api-latency-datamart-regeneration.md; keep the operative rule here concise and current.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
