MCP TrustOps
TrustOps turns this report into operational controls: freshness SLAs, authenticated validation, semantic benchmarks, policy exports, alert subscriptions, badges, cost/compliance metadata, and runtime routing. Fresh trusted index decisions stay separate from long-tail inventory so stale scores do not masquerade as current evidence.

MCP Runtime hosting
Verify Hosted MCP turns a trusted server report into a managed remote MCP endpoint with GitHub deployment provenance, sandbox policy, encrypted secrets, release history, rollback, and audit/usage events.

Client compatibility verdicts
Client compatibility only means the server shape can work with a client. Production trust decision and write-action publishing are evaluated separately so a client-compatible server can still be blocked for production.

Why compatibility is limited by client
Remediation checklist
OpenAI connectors expect OAuth for remote server auth.Dynamic client registration materially improves connector setup.Initialize must be reachable.tools/list must succeed.Transport compliance should be in good shape.OAuth interoperability should be strong.
Remediation checklist
Initialize must succeed or cleanly request auth.tools/list must succeed.Transport behavior should match Claude-compatible HTTP expectations.A useful Claude integration needs at least one exposed tool.search fetch only is not yet satisfiedwrite actions present is not yet satisfied
Remediation checklist
- No explicit blockers recorded.

Actionable remediation
| Severity | Remediation | Why it matters | Recommended action |
|---|---|---|---|
| Critical | Ensure tools/list succeeds consistently | Tools discovery is the minimum viable contract for most MCP clients and directories. | Make tools/list succeed unauthenticated when possible, or document the auth flow in the server card.Playbook
|
| Critical | Make initialize deterministic and client-friendly | If initialize fails or requires undocumented auth, many MCP clients cannot connect. | Allow initialize to succeed consistently, or return a deterministic auth-required response with clear metadata.Playbook
|
| Critical | Respond to initialize flow regressed | A client-visible initialize behavior changed for the worse. | Compare initialize responses between the latest two runs and restore the previous stable behavior.Playbook
|
| Critical | Respond to latest validation is failing | Core MCP flows did not validate successfully on the latest run. | Fix the failing checks first, then revalidate to confirm the recovery path.Playbook
|
| Critical | Respond to tools/list regressed | Tool discovery became less reliable on the latest run. | Compare tool enumeration outputs between runs and remove non-deterministic behavior.Playbook
|
| High | Align session and protocol behavior with Streamable HTTP expectations | Clients increasingly rely on MCP-Protocol-Version, session teardown, and expired-session semantics. | Align MCP-Protocol-Version, MCP-Session-Id, DELETE teardown, and expired-session handling with the transport spec.Playbook
|
| High | Associate roots, sampling, and elicitation with active client requests | Modern MCP guidance expects roots, sampling, and elicitation traffic to be tied to an active client request instead of arriving unsolicited on idle sessions. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| High | Expose /.well-known/oauth-protected-resource | Without a protected-resource document, OAuth clients cannot discover auth requirements reliably. | Serve /.well-known/oauth-protected-resource and point it at your authorization server metadata.Playbook
|
| High | Keep connector refreshes backward compatible | Managed connector clients freeze tool snapshots, so removed tools, new required args, and breaking output changes can break published integrations after refresh. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| High | Publish OAuth authorization-server metadata | Clients need authorization-server metadata to discover issuer, endpoints, and DCR support. | Publish /.well-known/oauth-authorization-server from your issuer and include registration_endpoint when supported.Playbook
|
| High | Publish a complete server card | Missing or incomplete server-card metadata weakens discovery, documentation, and trust signals. | Serve /.well-known/mcp/server-card.json and include tools, prompts/resources, homepage, and support links.Playbook
|
| High | Stop asking users to paste secrets directly | Public MCP servers should prefer OAuth or browser-based auth guidance over in-band secret collection. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| Medium | Adopt a current MCP protocol revision | Older protocol revisions reduce compatibility with newer clients and registry programs. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| Medium | Close connector-publishing gaps | Connector catalogs care about protocol recency, session behavior, auth clarity, and tool-surface stability. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| Medium | Document minimal scopes and return cleaner auth challenges | Modern clients expect granular scopes and step-up auth signals such as WWW-Authenticate scope hints. | Return granular scopes and WWW-Authenticate challenge hints instead of forcing overly broad auth upfront.Playbook
|
| Medium | Publish OpenID configuration | OIDC metadata improves token validation and client compatibility. | Expose /.well-known/openid-configuration with issuer, jwks_uri, and supported grants.Playbook
|
| Medium | Raise Adoption & Market score | Adoption clues and public evidence that the server is intended for external use. | Increase external documentation and directory coverage so users can discover and evaluate the server.Playbook
|
| Medium | Raise Interface Quality score | How well the tool/resource interface communicates and behaves under automation. | Improve schemas, error contracts, and recovery messages so agents can reason about the surface automatically.Playbook
|
| Medium | Reduce tool-surface churn | Frequent add/remove or output-shape drift makes published connectors and cached tool snapshots brittle. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| Medium | Repair prompts/list or stop advertising prompts | Prompt metadata should either work live or be removed from the advertised capability set. | Only advertise prompts if prompts/list works and prompt arguments are documented.Playbook
|
| Medium | Repair resources/list or stop advertising resources | Resource metadata should either work live or be removed from the advertised capability set. | Only advertise resources if resources/list works and resources expose stable URIs/types.Playbook
|
| Medium | Support resumable HTTP sessions cleanly | Modern MCP clients increasingly expect resumable session behavior on streamable HTTP transports. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| Low | Expose modern utility surfaces like completions, pagination, or tasks | Utility coverage improves interoperability with larger clients and long-lived agent workflows. | Expose completions, pagination, and task metadata where supported so larger clients can plan and resume work safely.Playbook
|
| Low | Publish newer MCP capability signals | Roots, sampling, elicitation, structured outputs, and related metadata improve client understanding and ranking. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
|
| Low | Publish or reconcile the server in the official MCP registry | Official registry presence improves discovery confidence and cross-source consistency. | Inspect the latest validation evidence and resolve the client-visible regression.Playbook
