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.

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 | $0.00048 | $0.00379 |
| Opus 5.5 | $0.00019 | $0.00152 |
| Sonnet 5.5 | $0.00010 | $0.00076 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
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 13d 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
Set up Rapidly
Rapidly runs as a remote MCP server at https://www.rapidly.co/mcp. The plugin already includes the connection, so setup is mostly signing in.
Run it
- Start the sign-in for the Rapidly connection. In Claude Code, that's
/mcpthen Rapidly. In Codex, complete the sign-in Codex shows for the plugin; if Rapidly was added withcodex mcp addinstead, runcodex mcp login rapidly. In ChatGPT, follow the connect prompt. - Pause only while the user signs in, chooses their Rapidly team and approves access. Don't report that Rapidly is connected until sign-in is complete.
- If the user doesn't have a Rapidly account, send them to https://www.rapidly.co/rapidly-mcp. It creates the account and team in a minute, with a 30-day free trial.
- Check the connection with a small, real request. Ask the user for one idea they're thinking about, or a company name and website, then use the
test-an-ideaskill.
Keep it safe
- Never ask the user to paste a token or password into chat.
- If their agent can't use OAuth, explain how to store a Rapidly personal token as a secure Authorization bearer token outside chat, source code and project files. The setup guide is at https://github.com/Exponentially-Platform/Rapidly-MCP/blob/main/docs/for-agents.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.

setup is a skill published in the GitHub repository Exponentially-Platform/Rapidly-MCP (2 stars, last pushed 6d ago), licensed MIT. It adds 48 tokens to every session and 379 once invoked, about $0.0002 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 2026-10-10.
