MongoDB Agent Skills is an official collection of skills and plugins that help AI coding agents work with MongoDB databases, including Atlas and self-managed deployments. Developers use it for query writing, schema design, query optimization, Atlas Search, and vector search. The catalogue entries are MongoDB’s own agent skills, plugins, and setup instructions.
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 | $0.00082 | $0.04681 |
| Opus 5 | $0.00041 | $0.02341 |
| Sonnet 5 | $0.00016 | $0.00936 |
| Haiku 4.5 | $0.00008 | $0.00468 |
Grade A, and why
mongodb-atlas-stream-processing 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 8d 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.
This is a copy
100% identical to mongodb-atlas-stream-processing — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MongoDB Atlas Streams
Build, operate, and debug Atlas Stream Processing (ASP) pipelines using four MCP tools from the MongoDB MCP Server.
Prerequisites
This skill requires the MongoDB MCP Server connected with:
- Atlas API credentials (
apiClientIdandapiClientSecret)
The 4 tools: atlas-streams-discover, atlas-streams-build, atlas-streams-manage, atlas-streams-teardown.
All operations require an Atlas project ID. If unknown, call atlas-list-projects first to find your project ID.
If MCP tools are unavailable
If the MongoDB MCP Server is not connected or the streams tools are missing, see references/mcp-troubleshooting.md for diagnostic steps and fallback options.
Tool Selection Matrix
atlas-streams-discover — ALL read operations
| Action | Use when |
|---|---|
list-workspaces |
See all workspaces in a project |
inspect-workspace |
Review workspace config, state, region |
list-connections |
See all connections in a workspace |
inspect-connection |
Check connection state, config, health |
list-processors |
See all processors in a workspace |
inspect-processor |
Check processor state, pipeline, config |
diagnose-processor |
Full health report: state, stats, errors |
get-networking |
PrivateLink and VPC peering details. Optional: cloudProvider + region to get Atlas account details for PrivateLink setup |
Pagination (all list actions): limit (1-100, default 20), pageNum (default 1).
Response format: responseFormat — "concise" (default for list actions) or "detailed" (default for inspect/diagnose).
atlas-streams-build — ALL create operations
| Resource | Key parameters |
|---|---|
workspace |
cloudProvider, region, tier (default SP10), includeSampleData |
connection |
connectionName, connectionType (Kafka/Cluster/S3/Https/Kinesis/Lambda/SchemaRegistry/Sample), connectionConfig |
processor |
processorName, pipeline (must start with $source, end with $merge/$emit), dlq, autoStart |
privatelink |
privateLinkConfig (project-level, not tied to a specific workspace) |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-atlas-stream-processing is a skill published in the GitHub repository mongodb/agent-skills (182 stars, last pushed 5d ago), licensed Apache-2.0. It adds 82 tokens to every session and 4,681 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to mongodb-atlas-stream-processing, differing in 0 lines, and is treated as a copy.
