Public, read-only Model Context Protocol (MCP) server for turva.dev, an agent-readiness audit and advisory service. It lets AI agents query turva.dev's service catalog, its own agent-readiness scores, the public web-security scan results for its domain, and its engagement principles, as structured JSON instead of scraped HTML.
The server is public on purpose: anyone can read exactly what it exposes before deciding anything.
https://mcp.turva.dev/mcp
Listed in the official MCP registry as dev.turva/turva-mcp, and in the Glama MCP directory (domain verified at /.well-known/glama.json).
Implements MCP protocol revision 2026-07-28. The SDK's legacy lane is left at its default, so a client on an older revision still works at the same endpoint. Transport is Streamable HTTP and the MCP endpoint is POST /mcp. The deprecated standalone SSE transport is not served.
Revision 2026-07-28 removed protocol sessions and the initialize handshake, so there is no session id and nothing to tear down. Each request carries the protocol revision and the client's capabilities in params._meta, and on the 2026-07-28 lane two headers are required, MCP-Protocol-Version naming the revision and Mcp-Method naming the same method as the body, with a third, Mcp-Name, on a tools/call to name the tool. server/discover reports what this server supports. A minimal discovery document carrying the name, transport and endpoint is published at GET / and GET /.well-known/mcp; the full signed MCP server card is at https://turva.dev/.well-known/mcp/server-card.json.
CORS differs by path on purpose. /mcp allows the browser origin https://turva.dev only, and answers 403 to any other origin; agents send no Origin header at all, so this restricts browser clients rather than agents. The card and discovery paths keep open CORS (Access-Control-Allow-Origin: *), because directories read them.
No authentication and no API key are required. All exposed data is public and read-only. Requests are rate limited to 100 per 60 seconds per client IP at the edge, answered with 429 and a Retry-After header past that, and the limiter fails open if it errors.
Four read-only tools. There are no write tools and no transaction tools. Each returns JSON as text content.
get_services: the service catalog (audit, advisory, implementation, agent operations, MCP server design), the engagement model, and pricing (fixed list prices for audit, advisory and implementation, others on request).get_agent_readiness: turva.dev's own agent-readiness score from an independent scanner, with category sub-scores, the measurement date, and verification links.get_security_evidence: public web-security scan results for turva.dev's own domain (Hardenize, Internet.nl), with the scan date.get_principles: the engagement principles, namely async-only, least access, results measured in scanner numbers, open and verifiable.
Data is served from static TypeScript objects bundled with the Worker, so every response is deterministic and depends on no external state. Scores carry a measured_at date and verification links, so any reader can compare a stored snapshot against a fresh scan.
The scores these tools return are turva.dev's own, measured by independent public scanners on 2026-08-01: 100/100 and Level 5 (Agent-Native) on isitagentready.com, Hardenize passing all 13 categories, and 98/100 on Internet.nl. Every response carries a measured_at date and a verification link, so a stored snapshot can be compared against a fresh scan. Re-run any scan yourself from the links in Verify below.
| Method and path | Response |
|---|---|
POST /mcp |
MCP over Streamable HTTP |
GET /mcp, DELETE /mcp |
405, no GET stream and no sessions since revision 2026-07-28 |
GET / |
Discovery JSON (name, transport, endpoint) |
GET /.well-known/mcp |
Discovery JSON |
GET /.well-known/glama.json |
Glama MCP directory domain verification |
OPTIONS /mcp |
200 CORS preflight from the MCP handler, 403 if the Origin is not allowed |
OPTIONS on any path other than /mcp |
204 CORS preflight |
GET, POST, PUT, DELETE, PATCH or HEAD on any other path |
404 |
GET and DELETE on /mcp answer 405: the GET stream and session termination went away with sessions in revision 2026-07-28. On the 2026-07-28 lane a request is refused with 400 and error code -32020 if a required header is absent, if Mcp-Method and the body name different methods, or if Mcp-Name and params.name name different tools, and a method this server does not declare, such as resources/list, answers 404 with -32601 rather than an empty success. A request carrying no MCP-Protocol-Version reaches the legacy lane instead, where that same undeclared method answers 200 carrying -32601 in the body. The discovery paths respond to any method.
Point any MCP client that supports Streamable HTTP at the endpoint. Example client config:
{
"mcpServers": {
"turva": {
"url": "https://mcp.turva.dev/mcp"
}
}
}Quick reachability check (returns the server card):
curl https://mcp.turva.dev/
On Windows PowerShell use curl.exe, since curl is an alias for Invoke-WebRequest.

A single Cloudflare Worker built on the Cloudflare Agents SDK serves the MCP endpoint through createMcpHandler. There is no Durable Object: the stateful implementation needed one, and it was deleted with the 2026-07-28 migration because the protocol no longer has sessions. Tool data lives in static TypeScript objects in the bundle. The server keeps no request log and never writes a request body, a client identity or tool input anywhere. Errors are returned as MCP protocol error responses. One console.error records a rate-limiter failure, so the fail-open path is diagnosable rather than silent; it carries no request data. Cloudflare Workers observability is switched off in wrangler.jsonc, so the platform does not collect invocation logs either.
The Worker is independent from the main turva.dev site, so an MCP change cannot affect the website.
Requires a Cloudflare account and the wrangler CLI.
cd turva-mcp
npm install
npx wrangler deployRoute the Worker to mcp.turva.dev under Workers & Pages, your-worker, Settings, Domains & Routes.
MIT licensed. Fork it, replace the static data objects with your own, then deploy.
