Need MCP Behavioral Conformance Governance
Need a way to control that an MCP server actually behaves like it is intended to behave at runtime, not just that it exists in a registry.

Persona Story:
Morgan, the security and compliance lead, just inherited an MCP governance mandate from the CIO on top of an existing API governance program. The team has GitHub and GitLab for inventory, but what is actually missing is a way to control that an MCP server behaves like it was intended to behave — that the runtime surface matches the declared intent, that it does not drift, and that policy can be enforced against actual MCP traffic rather than against a static spec.
Problem Context
- CIOs are extending existing API governance mandates to MCP without a clear “where to start” answer for the practitioner who owns the program
- Registry / inventory framings (where does the MCP live, who owns it) do not solve the runtime question of whether the MCP actually does what it claims
- Today’s controls are bolted onto pre-MCP API governance (Spectral lint, design reviews, manual final checks) and were never designed for behavior-at-runtime enforcement
- Practitioners have the language of the problem — “behavioral conformance” — but no tooling that maps to it
Problem Impact
- Governance teams cannot prove MCP servers stay within their stated intent, leaving CIO mandates unfulfillable in practice
- Pre-MCP design-time checks pass while runtime behavior drifts unchecked
- The first MCP-related incident inside the enterprise becomes a policy crisis rather than a technical fix
- Governance leads cannot answer the board-level question “are our MCPs actually under control?”
Naftiko Today
- Executable YAML capability specs declare an MCP’s intended consumes / exposes surface as a single auditable artifact, so “intended behavior” stops being a separate document and starts being the runtime contract itself
- Spectral ruleset (15 rules) and JSON Schema validation enforce design-time conformance against the capability spec before anything ships to runtime
- MCP exposure layer mediates between agents and upstream APIs at a controlled boundary where governance signals can be observed
- External bindings for secrets and configuration keep the MCP’s runtime credentials inside the governance perimeter rather than embedded in the server
Naftiko Tomorrow
- MCP auth support (Second Alpha) will allow policy to enforce who and what is allowed to invoke specific MCP surfaces, closing the runtime-conformance loop
- Tool annotations for readOnly / destructive / idempotent (Second Alpha) will give governance teams the behavioral metadata they need to write enforceable conformance rules
- Enterprise security with Keycloak and OpenFGA (v1.1) will provide IDP-backed fine-grained authorization so behavioral policy can be expressed per-tool per-consumer
- Fabric capability discovery (v1.1) will surface every MCP capability across the enterprise so the conformance program can target the whole estate, not just one server at a time
