MCP Server Atlassian Bitbucket tools 6

  • bb_getRead any Bitbucket data. Returns TOON format by default (30-60% fewer tokens than JSON). **IMPORTANT - Cost Optimization:** - ALWAYS use `jq` param to filter response fields. Unfiltered responses are very expensive! - Use `pagelen` query param to restrict result count (e.g., `pagelen: "5"`) - If unsure about available fields, first fetch ONE item with `pagelen: "1"` and NO jq filter to explore the schema, then use jq in subsequent calls **Schema Discovery Pattern:** 1. First call: `path: "/workspaces", queryParams: {"pagelen": "1"}` (no jq) - explore available fields 2. Then use: `jq: "values[*].{slug: slug, name: name, uuid: uuid}"` - extract only what you need **Output format:** TOON (default, token-efficient) or JSON (`outputFormat: "json"`) **Common paths:** - `/workspaces` - list workspaces - `/repositories/{workspace}` - list repos in workspace - `/repositories/{workspace}/{repo}` - get repo details - `/repositories/{workspace}/{repo}/pullrequests` - list PRs - `/repositories/{workspace}/{repo}/pullrequests/{id}` - get PR details - `/repositories/{workspace}/{repo}/pullrequests/{id}/comments` - list PR comments - `/repositories/{workspace}/{repo}/pullrequests/{id}/diff` - get PR diff - `/repositories/{workspace}/{repo}/refs/branches` - list branches - `/repositories/{workspace}/{repo}/commits` - list commits - `/repositories/{workspace}/{repo}/src/{commit}/{filepath}` - get file content - `/repositories/{workspace}/{repo}/diff/{source}..{destination}` - compare branches/commits **Query params:** `pagelen` (page size), `page` (page number), `q` (filter), `sort` (order), `fields` (sparse response) **Example filters (q param):** `state="OPEN"`, `source.branch.name="feature"`, `title~"bug"` **JQ examples:** `values[*].slug`, `values[0]`, `values[*].{name: name, uuid: uuid}` The `/2.0` prefix is added automatically. API reference: https://developer.atlassian.com/cloud/bitbucket/rest/
  • bb_postCreate Bitbucket resources. Returns TOON format by default (token-efficient). **IMPORTANT - Cost Optimization:** - Use `jq` param to extract only needed fields from response (e.g., `jq: "{id: id, title: title}"`) - Unfiltered responses include all metadata and are expensive! **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Create PR:** `/repositories/{workspace}/{repo}/pullrequests` body: `{"title": "...", "source": {"branch": {"name": "feature"}}, "destination": {"branch": {"name": "main"}}}` 2. **Add PR comment:** `/repositories/{workspace}/{repo}/pullrequests/{id}/comments` body: `{"content": {"raw": "Comment text"}}` 3. **Approve PR:** `/repositories/{workspace}/{repo}/pullrequests/{id}/approve` body: `{}` 4. **Request changes:** `/repositories/{workspace}/{repo}/pullrequests/{id}/request-changes` body: `{}` 5. **Merge PR:** `/repositories/{workspace}/{repo}/pullrequests/{id}/merge` body: `{"merge_strategy": "squash"}` (strategies: merge_commit, squash, fast_forward) The `/2.0` prefix is added automatically. API reference: https://developer.atlassian.com/cloud/bitbucket/rest/
  • bb_putReplace Bitbucket resources (full update). Returns TOON format by default. **IMPORTANT - Cost Optimization:** - Use `jq` param to extract only needed fields from response - Example: `jq: "{uuid: uuid, name: name}"` **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Update repository:** `/repositories/{workspace}/{repo}` body: `{"description": "...", "is_private": true, "has_issues": true}` 2. **Create/update file:** `/repositories/{workspace}/{repo}/src` Note: Use multipart form data for file uploads (complex - prefer PATCH for metadata) 3. **Update branch restriction:** `/repositories/{workspace}/{repo}/branch-restrictions/{id}` body: `{"kind": "push", "pattern": "main", "users": [{"uuid": "..."}]}` The `/2.0` prefix is added automatically. API reference: https://developer.atlassian.com/cloud/bitbucket/rest/
  • bb_patchPartially update Bitbucket resources. Returns TOON format by default. **IMPORTANT - Cost Optimization:** Use `jq` param to filter response fields. **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Update PR title/description:** `/repositories/{workspace}/{repo}/pullrequests/{id}` body: `{"title": "New title", "description": "Updated description"}` 2. **Update PR reviewers:** `/repositories/{workspace}/{repo}/pullrequests/{id}` body: `{"reviewers": [{"uuid": "{user-uuid}"}]}` 3. **Update repository properties:** `/repositories/{workspace}/{repo}` body: `{"description": "New description"}` 4. **Update comment:** `/repositories/{workspace}/{repo}/pullrequests/{pr_id}/comments/{comment_id}` body: `{"content": {"raw": "Updated comment"}}` The `/2.0` prefix is added automatically. API reference: https://developer.atlassian.com/cloud/bitbucket/rest/
  • bb_deleteDelete Bitbucket resources. Returns TOON format by default. **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Delete branch:** `/repositories/{workspace}/{repo}/refs/branches/{branch_name}` 2. **Delete PR comment:** `/repositories/{workspace}/{repo}/pullrequests/{pr_id}/comments/{comment_id}` 3. **Decline PR:** `/repositories/{workspace}/{repo}/pullrequests/{id}/decline` 4. **Remove PR approval:** `/repositories/{workspace}/{repo}/pullrequests/{id}/approve` 5. **Delete repository:** `/repositories/{workspace}/{repo}` (caution: irreversible) Note: Most DELETE endpoints return 204 No Content on success. The `/2.0` prefix is added automatically. API reference: https://developer.atlassian.com/cloud/bitbucket/rest/
  • bb_cloneClone a Bitbucket repository to your local filesystem using SSH (preferred) or HTTPS. Provide `repoSlug` and `targetPath` (absolute path). Clones into `targetPath/repoSlug`. SSH keys must be configured; falls back to HTTPS if unavailable.
