Critical alerts

High/critical-severity alerts

Production verdicts degrade quickly when high or critical-severity alerts are active.

Compatibility

Client readiness 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.

Client compatibility: ChatGPT

Not client-compatible

OpenAI connectors expect OAuth for remote server auth.; Dynamic client registration materially improves connector setup.; Transport compliance failed or did not complete successfully.; Step-up auth signals should be documented and connector-friendly.; OAuth interoperability should be strong.; The tool surface is not limited to search/fetch-style read tools.

Confidence: high (98.75)

Supporting sources: live_validation, history, server_card

Disagreements: none

initialize • OK
tools_list • OK
transport_compliance_probe • Error
step_up_auth_probe • Missing
connector_replay_probe • OK — Frozen tool snapshots must survive refresh.
request_association_probe • Missing — Roots, sampling, and elicitation should stay request-scoped.

Client compatibility: Claude

Not client-compatible

Transport behavior should match Claude-compatible HTTP expectations.; The tool surface is not limited to search/fetch-style read tools.; This client profile expects a read/search-only tool surface, but write, delete, or exec-capable tools are present.; OAuth is not configured, so this client cannot authenticate without additional setup.; Not yet safe for company-knowledge use: requires a search/fetch-only surface with no export, bulk, mutating, or high-blast-radius exposure.; Not yet safe for the Messages API remote MCP path: requires OAuth, a compatible connector profile, and no pending connector-refresh risk.

Satisfy OAuth, compatibility, and connector-refresh requirements before using the Messages API remote MCP path.

Write-safe publishing

Blocked

Risky write or non-read tools are exposed without a clear auth boundary.; Risky write or non-read tools lack confirmation/dry-run controls.; action_safety_probe is in warning.; Production readiness is blocked by an active alert: Tool snapshot changed.; Production readiness is blocked by an active alert: Auth mode changed.

Remediation checklist

Add a clearer auth boundary around risky write actions.
Add confirmation or dry-run semantics for the risky tools named in the action-safety evidence.
Confirm the flagged action-safety risk before treating this as write-safe.
Resolve the active alert: Tool snapshot changed.
Resolve the active alert: Auth mode changed.

Actionable remediation

Severity	Remediation	Why it matters	Recommended action
High	Add confirmation and dry-run semantics for risky actions	High-risk write, delete, exec, or egress tools should communicate safeguards clearly.	Add an explicit confirm/dry-run parameter or two-step confirmation flow to write, delete, exec, and egress-capable tools before they can make destructive changes. Playbook For each high-risk tool (delete, exec, or network-egress capable), add a `confirm`/`dry_run` parameter or a two-step confirmation flow. Document the safeguard in the tool's description so clients and agents know confirmation is required before execution. Revalidate and confirm `action_safety_probe` reports the safeguard as detected.
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 Return `Mcp-Session-Id` and `Mcp-Protocol-Version` headers consistently on streamable HTTP responses. Honor `DELETE` session teardown and return `404` when a deleted session is reused. Reject invalid protocol-version headers with `400 Bad Request`.
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 Serve `/.well-known/oauth-protected-resource` from the same host as the MCP endpoint. Point it at the authorization server metadata URL. Confirm clients receive consistent auth hints before tool execution.
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 Publish `/.well-known/oauth-authorization-server` from the issuer. Add `registration_endpoint` if DCR is supported. Verify issuer, authorization, token, and jwks metadata are all reachable.
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 Publish `/.well-known/mcp/server-card.json`. Include homepage, repository, support, tools, prompts/resources, and auth metadata. Revalidate the server after publishing the card.
High	Respond to auth mode changed	Auth mode changed from unknown to public.	Document the new auth posture and confirm protected-resource and challenge metadata still match reality.
High	Respond to tool snapshot changed	Tools were added, removed, or materially changed between the latest two validations.	Publish a first-class changelog for tool additions, removals, and breaking schema changes. Playbook Review the tool snapshot diff for adds, removals, required-arg changes, and output-schema drift. Publish a changelog before managed connector clients refresh their frozen tool snapshots. Revalidate after the changelog and connector metadata are in sync.
Medium	Adopt a current MCP protocol revision	Older protocol revisions reduce compatibility with newer clients and registry programs.	Advertise a current MCP protocol revision (2025-06-18 or later) in both the initialize response and the MCP-Protocol-Version header. Playbook Update the server's advertised protocol version to a current MCP revision (2025-06-18 or later). Return the negotiated version consistently in both the `initialize` response and the `MCP-Protocol-Version` header. Revalidate and confirm `protocol_version_probe` reports `ok`.
Medium	Close connector-publishing gaps	Connector catalogs care about protocol recency, session behavior, auth clarity, and tool-surface stability.	Resolve every blocker named by connector_publishability_probe, then rerun it before submitting or refreshing a connector listing. Playbook Review the blockers and failed criteria recorded by connector_publishability_probe. Correct the identified transport, authentication, server-card, or tool-stability gaps. Revalidate and require the probe to report no blockers before publishing the connector.
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 Advertise the narrowest viable scopes in OAuth metadata. Return `WWW-Authenticate` challenges with scope or insufficient-scope hints when additional consent is needed. Revalidate with both public discovery and auth-required flows.
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 Serve `/.well-known/openid-configuration` with `issuer`, `jwks_uri`, `authorization_endpoint`, and `token_endpoint`. List supported grant types in `grant_types_supported` and scopes in `scopes_supported`. Revalidate and confirm the `openid_configuration` check returns `ok`.
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.
Medium	Support resumable HTTP sessions cleanly	Modern MCP clients increasingly expect resumable session behavior on streamable HTTP transports.	Persist session state keyed by Mcp-Session-Id and honor Last-Event-ID on GET reconnects so clients can resume a dropped Streamable HTTP session. Playbook Persist session state keyed by `Mcp-Session-Id` so a client can reconnect after a dropped connection. Honor `Last-Event-ID` on GET reconnects to replay missed SSE events instead of erroring. Revalidate and confirm `session_resume_probe` no longer returns `warning`.
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 Advertise `completions`, pagination cursors, and `tasks` only when they are actually supported. Return `nextCursor` on large list operations when pagination is available. Document task support and whether it requires step-up auth.
Low	Publish newer MCP capability signals	Roots, sampling, elicitation, structured outputs, and related metadata improve client understanding and ranking.	Advertise only the advanced capabilities (roots, sampling, elicitation) you have actually implemented end to end in the initialize capabilities object. Playbook Add the capabilities you actually support (`roots`, `sampling`, `elicitation`) to the `capabilities` object returned from `initialize`. Only advertise a capability once the corresponding request/response flow is implemented end to end. Revalidate and confirm `advanced_capabilities_probe` reflects the updated capability set.
