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 | $0.00018 | $0.05716 |
| Opus 5.5 | $0.00007 | $0.02286 |
| Sonnet 5.5 | $0.00004 | $0.01143 |
| Haiku 4.5 | $0.00002 | $0.00572 |
Grade A, and why
mongodb_mcp_tools 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 1mo 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 — 786 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MongoDB MCP Server Tools
The MongoDB MCP Server allows you to interact with MongoDB clusters using natural language queries from AI clients that support MCP. This page describes the MCP Server tools.
Overview
The MongoDB MCP server provides the following tools categories:
-
Atlas tools, which perform operations on Atlas system resources, like organizations, projects, clusters, database user accounts, and retrieving performance recommendations.
-
Local Atlas tools, which allow you to list, connect to, create, and delete local Atlas deployments.
-
Database tools, which perform operations such as inserting, updating, and deleting documents, and running queries and aggregation pipelines.
MCP Server Atlas Tools
The Atlas tools are only available if you have set up Atlas API credentials as shown in MongoDB MCP Server Configuration.
The following table describes the Atlas tools:
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.

mongodb_mcp_tools is a skill published in the GitHub repository mongodb-partners/mongodb-gemini-extension (5 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 18 tokens to every session and 5,716 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.
