Need an Internal MCP Server Registry as an Allow-List
Enterprises need an internal registry of approved MCP servers that surfaces inside the developer IDE, acting as an allow-list so developers discover only vetted servers.

Persona Story:
Maya, the developer experience & AI engineering lead, needs to stand up an internal MCP server registry that acts as an allow-list of approved servers. Developers pull for MCP in their IDE; security cannot accept ungoverned public MCP servers because they can inject code into the LLM flow. The registry is the middle path: developers discover inside their IDE, but only see servers the enterprise has vetted.
Problem Context
- Developers see MCP content online and ask to use it in their IDE faster than security can vet individual servers
- Blocking MCP outright creates shadow-IT usage and pushes developers to ungoverned channels
- There is no default IDE surface today that distinguishes “approved by my company” from “public on the internet”
- Community open-source MCP registry exists but is not opinionated about enterprise allow-listing — each enterprise has to compose its own governed instance
- Registration must feel lightweight so approved servers reach developers faster than they can find unapproved ones
Problem Impact
- Supply-chain attack surface grows with every ungoverned MCP install in a developer IDE
- Security teams become a bottleneck reviewing MCP servers one request at a time
- Developer trust erodes when the only response to MCP curiosity is “no”
- Enterprise loses visibility into which MCP servers its developer population is actually using
- Approved integrations sit unused because developers never discover them
Naftiko Today
- Executable YAML capability specs give the enterprise a single, reviewable artifact per approved MCP server — the unit that the allow-list registers
- MCP exposure with Streamable HTTP and stdio transports lets Naftiko capabilities appear as native MCP servers that the IDE can list alongside any other approved entry
- VS Code Extension (Fleet) surfaces Naftiko capabilities directly in the IDE, giving Maya a sanctioned discovery path that parallels Copilot’s extensions window
- JSON Schema validation and Spectral ruleset enforce consistent structure across registered capabilities so the registry stays curated rather than chaotic
- External bindings for secrets/tokens/env vars keep credentials out of the registry entries, so approval is about behavior, not baked-in secrets
Naftiko Tomorrow
- Naftiko Shipyard MVP (Fleet Second Alpha) would provide the first-class enterprise MCP registry Maya needs, with governed publication and IDE-side discovery built in
- Tool annotations for readOnly/destructive/idempotent (Second Alpha) would let the registry expose risk posture at listing time so developers pick the right tool without escalation
- MCP auth support (Second Alpha) would ensure every server in the allow-list enforces standardized auth rather than relying on trust at registration
- Fabric capability discovery (v1.1) would enable enterprise-wide search across registered MCP servers, making the allow-list the default surface rather than a secondary reference
- JSON Schema Store publication (GA) would let third parties publish registry-compatible specs that enterprises can opt into without custom format work
