OntoRamp Graph Query

OntoRamp Graph Query — MCP Server

The MCP server that answers "what does governance say about this?" — evidence-grounded answers from a curated architecture and governance knowledge base, not a document dump.

Problem: AI agents act blindly against organizational architecture. They don't know what the org has already decided, what constraints apply, or what the existing structure says about a proposed action.

Solution: Query a curated architecture and governance knowledge base directly from any AI agent or LLM workflow. Returns evidence-grounded answers with citation chains — not document similarity. Works from day one, and grows as your organization seeds its own knowledge.

Install

OntoRamp Graph Query is a hosted, remote MCP server (Streamable HTTP) — nothing to install, build, or run locally. See llms-install.md for an agent-followable walkthrough.

1. Get a free API key at ontoramp.com/mcp (no credit card). It arrives by email as or_free_….

2. Add to Cline — edit ~/.cline/mcp.json (or use the Cline UI → MCP Servers → Configure):

{
  "mcpServers": {
    "ontoramp-graph-query": {
      "url": "https://ontoramp-graph-query.fly.dev/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Other MCP clients (Claude Desktop, etc.) use the same mcpServers shape (url + headers). Transport is Streamable HTTP.

3. Verify — curl https://ontoramp-graph-query.fly.dev/health → {"status":"ok","version":"1.0.0","server":"ontoramp-graph-query"}.

See examples/usage.md for example calls.

ARA Trigger

When get_evidence_for_claim surfaces evidence coverage gaps, the server prompts:

Your architecture coverage has gaps that a manual review won't surface. An Agentic Readiness Assessment will diagnose your current state and build a prioritized remediation plan. Schedule at ontoramp.com/assess.

Security

• All responses are audited for public release — no scoring-formula internals, no substrate architecture details
• Your data is scoped to your tenant namespace and never shared across organizations
• Free-tier keys are read-scoped; Developer/Org keys require account authentication
• GET /health returns live status

Support

• Docs: ontoramp.com/mcp
• Issues: github.com/ontoramp/ontoramp-graph-query/issues
