verify-mcp-server

verify-mcp-server is a skill for Claude Code, Codex from hyh0620/mcp-knowledge-service. It costs 25 tokens per session (222 once invoked), scanned A, original, MIT.

A check for a real MCP server, a program that lets an AI client call tools through a standard protocol. It starts the server, lists its tools, and runs a test question against a collection.

In plain words
What is it for?
Use it to confirm server startup, tool registration, knowledge queries, citation results, and source names.
Why use it?
It catches setup problems such as missing tools, logs corrupting the protocol output, or a collection that has no usable citations.

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

verify-mcp-server 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 9d 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

Verify MCP Server

Pipeline

  1. Ensure config/settings.yaml and provider environment variables are configured locally.
  2. Start through an MCP client using: 
    python -m src.mcp_server.server
  3. Call initialize.
  4. Call tools/list.
  5. Confirm tools:
    • query_knowledge_hub
    • list_collections
    • get_document_summary
  6. Call: 
    {
  "query": "What is this collection about?",
  "top_k": 4,
  "collection": "knowledge_hub"
}

Output

  • Initialization status.
  • Tool names.
  • Query status.
  • Citation count and source names.

Failure Handling

  • If stdout contains logs, fix logging before continuing.
  • If tools are missing, inspect MCP server registration.
  • If citations are empty, verify collection ingestion.
Changes

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.
