OntoRamp Graph Query

OntoRamp Graph Query — MCP Server

> The only MCP server that answers "what does our architecture say about this?" — grounded in your organization's actual documented structure, 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 your organization's architecture and governance constraints directly from any AI agent or LLM workflow. Returns architecture-grounded answers with evidence chains — not document similarity.

Tools

| Tool | Description | Tier | |------|-------------|------| | query_architecture | Query organizational architecture for answers grounded in documented structure | Free | | get_constraint_signals | Surface governance constraints relevant to a proposed action or decision | Free | | find_dependencies | Trace dependencies between systems and components in your architecture | Developer+ | | get_evidence_for_claim | Return evidence chains supporting or contradicting an architectural claim | Developer+ | | request_assessment | Submit an Agentic Readiness Assessment request | All tiers, rate-limit exempt |

Tiers

| Tier | Price | Limits | Features | |------|-------|--------|----------| | Free | — (no credit card) | 10 queries/day | query_architecture + get_constraint_signals | | Developer | $0.015/call | Unlimited | All tools · Evidence provenance · Query history | | Org | $249/mo flat | Unlimited | Aggregate architecture health · Cross-agent pooling · ARA pre-population |

request_assessment is exempt from rate limits on every tier.

Install

OntoRamp Graph Query is a hosted, remote MCP server (Streamable HTTP) — nothing to install, build, or run locally. See [llms-install.md](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](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/assessment.

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/MatthewDavisAIArchitect/ontoramp-graph-query/issues
