Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/debugmcp/mcp-debugger/agents-mdgit clone --depth 1 https://github.com/debugmcp/mcp-debuggerWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00791 | $0.00791 |
| Opus 5 | $0.00396 | $0.00396 |
| Sonnet 5 | $0.00158 | $0.00158 |
| Haiku 4.5 | $0.00079 | $0.00079 |
Grade A, and why
mcp-debugger 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
src/contains the TypeScript CLI and server core that power the Debug MCP runtime.packages/hosts workspace modules (@debugmcp/shared,adapter-mock,adapter-python,adapter-ruby,adapter-javascript,adapter-rust,adapter-go,adapter-java,adapter-dotnet,adapter-cpp,codelldb-common,mcp-debugger) with their ownsrc/trees.tests/is grouped by scope:core/,adapters/*/,e2e/, plus shared utilities intests/test-utils/and fixtures undertests/fixtures/.docs/covers design notes;examples/hosts adapter recipes;scripts/stores CI helpers.- Build artifacts land in
dist/; recorded assets and Docker helpers live inassets/anddocker/.
Build, Test, and Development Commands
pnpm installsets up the monorepo (respect the generatedpnpm-lock.yaml).pnpm buildcompiles every package and emits the aggregateddist/index.js.pnpm devlaunches the TypeScript entry point viats-nodefor quick feedback.pnpm testperforms a full build, ensures Docker images are ready, and runs Vitest across all suites.- Targeted runs:
pnpm test:unit,pnpm test:integration,pnpm test:e2e,pnpm test:coverage. pnpm lintapplies the workspace-wide ESLint config; add:fixto auto-format when safe.
Coding Style & Naming Conventions
- Source files use ES modules, TypeScript strict mode, and two-space indentation; prefer
PascalCasefor classes,camelCasefor functions, andSCREAMING_SNAKE_CASEfor constants. - Align new utilities with the patterns in
src/utils/(utility modules — mix of pure functions and service classes — with explicit exports). - ESLint (
eslint.config.js) enforces TypeScript recommended rules, unused-variable patterns, and environment-specific overrides (e.g., relaxed rules for test files and mock utilities)—run it before opening a PR. - Avoid default exports; monorepo packages rely on named exports for tree shaking and test isolation.
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.

mcp-debugger AGENTS.md is an instructions file published in the GitHub repository debugmcp/mcp-debugger (159 stars, last pushed 2d ago), licensed MIT. It adds 791 tokens to every session, about $0.0040 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
