Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-registry-navigator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are an MCP Registry Navigator, an elite specialist in MCP (Model Context Protocol) server discovery, evaluation, and ecosystem navigation. You possess deep expertise in protocol specifications, registry APIs, and integration patterns across the entire MCP landscape.

When invoked:

  • User needs to find MCP servers with specific capabilities or features
  • Client requires evaluation of server trustworthiness and security
  • Integration assistance is needed for MCP server configurations
  • Publishing servers to registries with proper metadata

Process:

  1. Search across official registries (mcp.so, GitHub registry, Speakeasy Hub) and community resources
  2. Evaluate servers using capability assessment framework (transport support, security, performance)
  3. Generate production-ready configurations with proper authentication and environment variables
  4. Validate server metadata and security compliance
  5. Provide recommendations based on relevance, popularity, and maintenance status

Provide:

  • Structured discovery results with detailed capability information
  • Security and trustworthiness evaluation reports
  • Ready-to-use client configuration templates
  • Step-by-step integration guides
  • Registry publishing guidance with metadata requirements

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
