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 5.1 | $0.03927 | $0.03927 |
| Opus 5.5 | $0.01571 | $0.01571 |
| Sonnet 5.5 | $0.00785 | $0.00785 |
| Haiku 4.5 | $0.00393 | $0.00393 |
Grade A, and why
gitlab-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 today.
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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
gitlab-mcp-server — Agent Quick Reference
MCP server in Go that exposes GitLab REST + GraphQL as MCP tools, resources, and prompts. Communicates via stdio (default) or HTTP. Catalog-first tool registration: 180 sub-packages under
internal/tools/, with three runtime surfaces (dynamicdefault,meta,individual).
Read first

Project rules and context, ADR list, agents/skills catalog, docs/development index |
.github/copilot-instructions.md |
Auto-loaded by VS Code Copilot; has the language policy, env var table, E2E recipes |
.github/instructions/*.md |
Auto-applied coding standards (go, MCP, OWASP, comments, code review) |

docs/development/adr |
Architectural Decision Records (catalog-first is ADR-0004) |
site/src/content/docs/ |
User documentation: one page per slug, each with its Spanish twin under es/ |
That site, published at https://docs.jmrp.io/gitlab-mcp-server/, is the only
home of the user documentation; docs/ keeps docs/development, for
contributors (ADR-0025).
The canonical agents live under .github/agents/ and the skills under
.github/skills/; .claude/agents/ and .claude/skills/ hold a symbolic
link to each for Claude Code. OpenCode wiring is per developer: opencode.json and
.opencode/ are git-ignored and never committed.
Hard invariants
- Catalog-first registration. For ordinary GitLab API actions, add or
update domain-local
ActionSpecs and handlers. Do not add package-localRegisterToolsfunctions or ad hocmcp.AddToolcalls. The catalog ininternal/tools/action_catalog.goprojects everything into meta, dynamic,gitlab://tools, audits, LLM files, and individual tool surfaces. (ADR-0004.) - English-only artifacts. Every file committed to this repo must be
in English, including doc comments, ADRs, branches, commits, and MCP
tool descriptions. The one exception is the Spanish half of the user
documentation: the twin pages under
site/src/content/docs/es/, and the Spanish text the site and the generators that write it keep beside the English (anesfield, alabelEs,site/src/content/i18n/es.json). Chat with the developer in any language you want. - Conventional commits.
feat:,fix:,docs:,test:,refactor:,chore:. Use thegit-commitskill (.claude/skills/git-commit/) for auto-detected type/scope. - Coverage target: maximum possible, 100% when feasible. CI fails
below 90% total coverage (
COVERAGE_MINin.github/workflows/ci.yml); in practice the team pushes per-package coverage to 100% unless there is a hard blocker (generated code, third-party interfaces). When you cannot reach 100% on a function, add a documented reason at the call site and prefer table-driven tests that exercise both happy and error paths.
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.
