Feature & Specification Comparison
Tools & Capabilities Breakdown
MCP Server Atlassian Confluence Tools (5)
conf_get
Read any Confluence 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 `limit` query param to restrict result count (e.g., `limit: "5"`)
- If unsure about available fields, first fetch ONE item with `limit: "1"` and NO jq filter to explore the schema, then use jq in subsequent calls
**Schema Discovery Pattern:**
1. First call: `path: "/wiki/api/v2/spaces", queryParams: {"limit": "1"}` (no jq) - explore available fields
2. Then use: `jq: "results[*].{id: id, key: key, name: name}"` - extract only what you need
**Output format:** TOON (default, token-efficient) or JSON (`outputFormat: "json"`)
**Common paths:**
- `/wiki/api/v2/spaces` - list spaces
- `/wiki/api/v2/pages` - list pages (use `space-id` query param)
- `/wiki/api/v2/pages/{id}` - get page details
- `/wiki/api/v2/pages/{id}/body` - get page body (`body-format`: storage, atlas_doc_format, view)
- `/wiki/rest/api/search` - search content (`cql` query param)
**JQ examples:** `results[*].id`, `results[0]`, `results[*].{id: id, title: title}`

conf_post
Create Confluence 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 page:** `/wiki/api/v2/pages`
body: `{"spaceId": "123456", "status": "current", "title": "Page Title", "parentId": "789", "body": {"representation": "storage", "value": "<p>Content</p>"}}`
2. **Create blog post:** `/wiki/api/v2/blogposts`
body: `{"spaceId": "123456", "status": "current", "title": "Blog Title", "body": {"representation": "storage", "value": "<p>Content</p>"}}`
3. **Add label:** `/wiki/api/v2/pages/{id}/labels` - body: `{"name": "label-name"}`
4. **Add comment:** `/wiki/api/v2/pages/{id}/footer-comments`
