Project instructions for a local MCP server that gives an AI agent controlled access to Bitbucket Cloud. Bitbucket Cloud is a service for hosting code, branches, pull requests, and build pipelines.

In plain words
What is it for?
Guiding agent work with Bitbucket pull requests, code, branches, pipelines, webhooks, and variables while requiring changes to protected branches to go through pull requests.
Why use it?
They define how to use the server safely, including required permissions, environment settings, and rules for protected branches.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md.

This is marcusyoda/bitbucket-mcp's own configuration. It tells Claude Code how to work on bitbucket-mcp 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 bitbucket-mcp 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

bitbucket-mcp CLAUDE.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 7d 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.

CLAUDE.md, bitbucket-mcp

Regras deste projeto. Seguir à risca. Ao trabalhar neste repo ou ao operar o MCP em qualquer projeto, respeitar tudo abaixo.

O que é

MCP server (TypeScript, ESM, stdio) pro Bitbucket Cloud. Existe porque o MCP oficial da Atlassian cobre só Jira + Confluence, não o Bitbucket. Dá superfície de tools controlada e payloads enxutos pra PRs, código, branches, pipelines, webhooks e variáveis, em vez de chamada solta na REST API.

Auth: Atlassian API token scoped, Basic email:token. Workspace e repo vêm das env (BITBUCKET_WORKSPACE, BITBUCKET_DEFAULT_REPO), sem default embutido.

Regras de segurança (à risca)

  1. Scopes do token: exatamente os 8 de PERMISSIONS.md. Nunca pedir nem assumir admin:* ou delete:* sem decisão humana explícita registrada em PERMISSIONS.md. Tools de variável dão 403 sem admin: isso é esperado, não é bug, não tentar contornar.
  2. Branches protegidas (BITBUCKET_PROTECTED_BRANCHES, default main,dev) nunca são mutadas direto. git_push, git_rebase, delete_branch, create_branch recusam mirar elas, e confirm NÃO fura isso. Mudança pra main/dev só via PR.
  3. merge_pull_request para main/dev é permitido, mas só com confirm:true. É o caminho sancionado.
  4. Ações destrutivas exigem confirm:true: merge, decline, delete_*, stop_pipeline, git_commit, git_push, comentário inline (add_pr_comment com inline_path), criar variável secured.
  5. BITBUCKET_READ_ONLY=true bloqueia todo write/destrutivo antes de tocar a API. Usar em sessões de só leitura (review, drift, conferência).
  6. Valores de variável secured nunca são retornados nem logados (write-only na API).
  7. git_*/clone usam a chave SSH, não o token. Push pra protegida é bloqueado em 3 camadas: guarda do MCP + branch restrictions server-side + sem rebase de branch protegida.

Convenções

  • Sem travessão nem meia-risca em nenhum texto: código, commits, comentários de PR, docs. Usar vírgula, dois pontos, parênteses ou quebra de linha.
  • Comentário de PR: texto em português + Conventional Comments. Label em inglês, corpo em PT. Ex: **suggestion (non-blocking):** extrair isto pra um helper. Labels: praise, nitpick, suggestion, issue, todo, question, thought, chore, note.
  • Estilo de código: pnpm, ESM, strict TS, single quotes, semicolons, width 100, build tsup ESM.
  • Mensagem de commit: conventional, assunto curto, sem em dash.

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.
