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 | $0.00027 | $0.00355 |
| Opus 5.5 | $0.00011 | $0.00142 |
| Sonnet 5.5 | $0.00005 | $0.00071 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
gmail-mcp 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.
What it actually says
GmailMCP
GmailMCP is a Model Context Protocol (MCP) server. Use it to rank, triage, and draft replies for a Gmail inbox. The same tools are also reachable over a CLI and a plain HTTP API; behaviour is identical across all three transports.
Connect
Add the MCP server to your client, then discover its tools.
- Endpoint (streamable HTTP):
https://mcp.gmailmcp.com/mcp - Server name:
gmail-mcp - Discovery metadata:
https://gmailmcp.com/.well-known/mcp.json
Use
-
List the available tools with the MCP
tools/listmethod. -
Call a tool with
tools/calland typed JSON arguments. For example, to triage the inbox:{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "gmail_curate_inbox", "arguments": { "limit": 3 } } } -
The server returns structured output (e.g. threads ranked by an importance score, with a flag for whether a draft reply was prepared).

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.

gmail-mcp is a skill published in the GitHub repository Edison-Watch/Custom-MCPs (0 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 355 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 2026-08-31.
