Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00729 |
| Opus 5 | $0.00015 | $0.00365 |
| Sonnet 5 | $0.00006 | $0.00146 |
| Haiku 4.5 | $0.00003 | $0.00073 |
Grade A, and why
metamcp 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MetaMCP tools (@mentu/[email protected] → 4 tools)
mcp_discover— search tools / list servers (first call can cold-start many children — prefermcp_callwhen you know the server)mcp_provision— resolve capability → servermcp_call— call a child tool (prefer this)mcp_execute— multi-step JS sandbox over servers
0.5.x docs mention skill tools; installed 0.4.1 exposes the four core tools only.
How to call (examples)
Direct (no MetaMCP):
mcp__agentmemory__memory_recall/memory_remember/ …mcp__gitnexus__impact/query/context/detect_changes
Via MetaMCP:
mcp_discover { "query": "screenshot" }
mcp_call {
"server": "chrome-devtools",
"tool": "take_screenshot",
"args": { ... }
}
mcp_call {
"server": "github",
"tool": "<tool_name>",
"args": { ... }
}
mcp_call {
"server": "perplexity",
"tool": "perplexity_search",
"args": { "query": "..." }
}
mcp_call {
"server": "context7",
"tool": "resolve-library-id", # or docs tool name from discover
"args": { ... }
}
Rules
- Prefer direct gitnexus + agentmemory — do not route them through MetaMCP.
- For anything else:
mcp_discoveronce if unsure, thenmcp_call. - Do not invent host-level MCP servers; add children only in
metamcp.mcp.json. - After editing child config, restart CLI sessions (hot-reload may apply inside MetaMCP only).
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.

metamcp is a skill published in the GitHub repository VKirill/claude-lane-stack (115 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 729 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
