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 | $0.00090 | $0.01219 |
| Opus 5.5 | $0.00036 | $0.00488 |
| Sonnet 5.5 | $0.00018 | $0.00244 |
| Haiku 4.5 | $0.00009 | $0.00122 |
Grade A, and why
run-mcp-servers 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.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Running the MCP servers
An MCP server's user is a protocol client, so "running" it means completing a
handshake and calling tools — not importing the module, not pytest. Drive it
the way Claude Code will.
Two ways, same underlying client:
scripts/drive_servers.py— headless smoke test, exits non-zero on failure. Use for verification.uv run mcp-lab-ui— the dashboard at http://127.0.0.1:8765. Use when the user wants to see it, or when explaining how MCP works.
The dashboard
docker compose up -d # Postgres first, or 3 of 4 servers fail
uv run mcp-lab-ui # http://127.0.0.1:8765
Long-running — start it in the background and tell the user the URL; do not
wait on it. Servers connect asynchronously, so the page fills in over a few
seconds; it polls until nothing is connecting.
Panes: servers (grouped by control model), inspector (invoke anything; shows the
input schema the model receives), wire log (live JSON-RPC frames, click to
expand). The tap lives in src/mcp_lab_ui/hub.py::_tap — memory streams spliced
between stdio_client and ClientSession, logging each SessionMessage as it
passes. Frames are genuine, not reconstructed.
It's unauthenticated and can call every tool on every connected server, including Docker writes. Localhost only — never bind it outward.
The one command
docker compose up -d # Postgres must be up first
uv run python scripts/drive_servers.py # all four
uv run python scripts/drive_servers.py postgres # just one
Exit code 0 = every configured server responded. It reads .mcp.json directly,
so it tests the real config rather than a copy that can drift.
Expected output: notes 4 tools, postgres 9 tools with write refused: YES, docker 19 tools, github skipped unless a PAT is set.
write refused: NO is the one result that matters most. It means the
read-only Postgres setup has regressed — treat it as a failure even though the
server responded. Both layers are described in docs/SERVERS.md.
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.

run-mcp-servers is a skill published in the GitHub repository nikhilpatil79/mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 90 tokens to every session and 1,219 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
