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

How do I install OntoRamp Graph Query?

It runs as a remote server. In Claude Code: claude mcp add --transport http ontoramp-graph-query 'https://ontoramp-graph-query.fly.dev/mcp' --header 'Authorization: <Bearer API key. Get your free key at ontoramp.com/mcp>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does OntoRamp Graph Query need an API key?

Yes. It expects Authorization, which you set in its configuration.

Is OntoRamp Graph Query open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains OntoRamp Graph Query?

It is published by MatthewDavisAIArchitect. AI.tn lists it but does not maintain or endorse it.
