Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00626 |
| Opus 5.5 | $0.00007 | $0.00250 |
| Sonnet 5.5 | $0.00004 | $0.00125 |
| Haiku 4.5 | $0.00002 | $0.00063 |
Grade A, and why
MCP Server Setup 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 10d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MCP Server Setup
Use MCP when an external server should provide tools to Meerkat. MCP server configuration controls tool discovery and transport; it does not move semantic ownership away from the server or Meerkat runtime.
Operating Rules
- Use
rkat mcp addto register servers in project or user config. Project is the default scope;--scope localis an alias for project. - Use stdio for local command-backed servers, streamable HTTP for modern network servers, and SSE only for legacy servers that require it.
- Use
rkat mcp listandrkat mcp getto inspect configured servers. - Use
rkat mcp login <name>for OAuth-protected HTTP servers. Do not paste bearer tokens into prompts or command arguments. - Login needs an account selection, written by
rkat mcp add:--oauth-account-selection discover(bind the account the provider verifies at the first login),--oauth-account <SUBJECT_ID>(a known provider subject ID, not an email) or--oauth-account-selection unverified(resource-bound access with no account evidence). Never pickunverifiedfor the user: it is their explicit choice, for example afterdiscoveris refused because the server publishes no account evidence. - Project configuration wins when the same server name exists in both scopes.
Specify
--scopewhen removing an ambiguous name. - Start or resume a session to load configured MCP tools into the agent.
- For live session mutation, use JSON-RPC
mcp/add,mcp/remove, andmcp/reload, or the REST/sessions/{id}/mcp/*routes. Mutations are staged and take effect at a turn boundary; editing config does not mutate an active session mid-turn. - Keep durable work state in WorkGraph and time-based wakeups in Schedule. MCP tools are actuators or external integrations.
Examples
rkat mcp add files -- npx -y @modelcontextprotocol/server-filesystem .
rkat mcp add issue-api --url https://mcp.example.com --oauth-account-selection discover
rkat mcp login issue-api
rkat mcp list
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.

MCP Server Setup is a skill published in the GitHub repository lukacf/meerkat (23 stars, last pushed today), licensed Apache-2.0. It adds 18 tokens to every session and 626 once invoked, about $0.0001 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 2026-08-30.
Other skills, from other repositories
stuck
Diagnose frozen, stuck, or slow Qwen Code sessions on this machine. Scans for problematic processes, high CPU/memory usage, hung subprocesses, and debug logs. Use /stuck or /stuck to focus on a specific process.

Guide for running end-to-end tests of the Qwen Code CLI, including headless mode, MCP server testing, and API traffic inspection. Use this skill whenever you need to verify CLI behavior with real model calls, reproduce user-reported bugs end-to-end, test MCP tool integrations, or inspect raw API request/response…
structured-debugging
Hypothesis-driven debugging methodology for hard bugs. Use this skill whenever you're investigating non-trivial bugs, unexpected behavior, flaky tests, or tracing issues through complex systems. Activate proactively when debugging requires more than a quick glance — especially when the first attempt at a fix didn't…
desktop-brand-builder
Generate a branded Qwen Code desktop package from the Tauri desktop shell using a minimal brandId and logo. Use when the user wants a custom, white-label, or rebranded desktop client, installer, DMG/EXE/AppImage/deb, or one-click brand build on top of packages/desktop.
batch-api
Prepare a many-file, single-turn transform (translate, rewrite, extract) as a plan and submit it to the asynchronous, half-price DashScope Batch API; results are delivered as new files hours later. Invoke explicitly with /batch-api.
repo-hygiene
Use when the scheduled repo-hygiene workflow runs from GitHub Actions (or an operator dry-run) to scan the repository for small, certain docs/test/code hygiene issues and fix them as one batched branch.
