Ceph Issue Intelligence KB

Searchable knowledge base of 14,600+ Ceph issues from IBM Ceph JIRA and Red Hat KB. Ships pre-built — clone, install, and immediately search known issues, workarounds, and fixes from your AI agent.

Setup

1. Clone and install

git clone https://github.com/pdhiran/ceph-issue-kb.git
cd ceph-issue-kb
pip install -e .

2. Connect your agent

Choose the integration that matches your agent:

---

Cursor — add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "ceph-issue-kb": {
      "command": "python3",
      "args": ["-m", "ceph_issue_kb.server.mcp_server"],
      "cwd": "/path/to/ceph-issue-kb"
    }
  }
}

Restart Cursor. The MCP server starts automatically and pulls the latest issue data on startup — no manual git pull needed.

To disable auto-update, add "--no-auto-update" to args.

---

Claude Desktop — start the server, then add to claude_desktop_config.json:

python -m ceph_issue_kb.server.mcp_server --transport sse --port 8083

{
  "mcpServers": {
    "ceph-issue-kb": { "url": "http://localhost:8083/sse" }
  }
}

---

Continue / Cline / Windsurf — start the server and point to the SSE endpoint:

python -m ceph_issue_kb.server.mcp_server --transport sse --port 8083

Connect to http://localhost:8083/sse in the tool's MCP settings.

---

IBM Bob — Bob supports MCP over SSE natively:

python -m ceph_issue_kb.server.mcp_server --transport sse --host 0.0.0.0 --port 8083

Add to Bob's .bob/mcp.json:

{
  "mcpServers": {
    "ceph-issue-kb": {
      "url": "http://localhost:8083/sse",
      "transport": "sse"
    }
  }
}

If running on a shared server, replace localhost with the hostname.

---

REST API — for LangChain, CrewAI, or CI pipelines:

python -m ceph_issue_kb.server.rest_api --host 0.0.0.0 --port 8200

# Search issues
curl -X POST http://localhost:8200/api/search_issues \
  -H "Content-Type: application/json" \
  -d '{"query": "OSD slow ops", "component": "rados"}'

# Check if an error is a known issue
curl -X POST http://localhost:8200/api/is_known_issue \
  -H "Content-Type: application/json" \
  -d '{"error_message": "FAILED ceph_assert(googly > 0)", "version": "19.2.0"}'

# Find workaround
curl -X POST http://localhost:8200/api/find_workaround \
  -H "Content-Type: application/json" \
  -d '{"query": "too many PGs per OSD"}'

# Health check
curl http://localhost:8200/health

See BOB_INTEGRATION_GUIDE.md for the full REST API reference and agent integration examples.

3. Use it

Once connected, agents automatically check for known Ceph issues. You can also ask directly:

• "Is FAILED ceph_assert(googly > 0) a known issue?"
• "Find workarounds for OSD slow ops during recovery"
• "Search for issues related to HEALTH_WARN too many PGs per OSD"
• "What are the hot issues in the rgw component?"
• "Find issues with this stacktrace: #0 in BlueStore::_do_write"

Available Tools

Tool	Description
search_issues	Search issues across all sources with optional filters
find_similar_issue	Find issues similar to a given problem description
is_known_issue	Check if an error message matches a known issue
find_workaround	Search for known workarounds
find_fix	Search for known fixes, commits, PRs
find_related_issues	Get related/duplicate/linked issues
search_stacktrace	Find issues with similar stacktraces
search_health_warning	Find issues related to a health warning
hot_issues	Most active recent issues by component

Active Sources

Source	Issues	Description
IBM Ceph JIRA	14,037	Internal Ceph bug tracker and feature requests
Red Hat KB	600	Customer-facing knowledge base articles

The knowledge base is updated daily by the maintainer with the latest bugs and articles. Your MCP server automatically pulls new data every 12 hours — no action needed on your part.

VS Code Extension

Coming soon. See ceph-doc-kb and ceph-command-kb for existing VS Code extensions that complement this knowledge base.

Documentation

Document	Description
SPEC.md	MCP platform contract and entity schema
DEVELOPMENT.md	Architecture, source tree, maintainer guide

Running All Ceph MCPs Together

Three specialized MCPs work together as the Ceph Engineering Intelligence Platform:

MCP	Purpose	SSE Port	Repo
ceph-cmd-kb	Commands, configs, test validation	8081	ceph-command-kb
ceph-doc-kb	Documentation search, code examples	8082	ceph-doc-kb
ceph-issue-kb	Known issues, workarounds, fixes	8083	ceph-issue-kb

Start all three for SSE clients (Bob, Claude Desktop, etc.):

python -m ceph_command_kb.server.mcp_server --transport sse --port 8081 &
python -m ceph_doc_kb.server.mcp_server --transport sse --port 8082 &
python -m ceph_issue_kb.server.mcp_server --transport sse --port 8083 &

Combined agent config (.bob/mcp.json, claude_desktop_config.json, etc.):

{
  "mcpServers": {
    "ceph-cmd-kb": { "url": "http://localhost:8081/sse", "transport": "sse" },
    "ceph-doc-kb": { "url": "http://localhost:8082/sse", "transport": "sse" },
    "ceph-issue-kb": { "url": "http://localhost:8083/sse", "transport": "sse" }
  }
}
