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 | $0.00012 | $0.01951 |
| Opus 5 | $0.00006 | $0.00975 |
| Sonnet 5 | $0.00002 | $0.00390 |
| Haiku 4.5 | $0.00001 | $0.00195 |
Grade A, and why
mongodb 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 5d 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.

MongoDB Skill
Query and manage MongoDB databases through a containerized mongosh client.
Overview
This skill provides AI agents with MongoDB database access through a Docker-based mongosh (MongoDB Shell) client. Run queries, manage collections, perform aggregations, and analyze data.
When to Use This Skill
- Execute MongoDB queries and aggregations
- Manage collections and indexes
- Insert, update, and delete documents
- Analyze data with aggregation pipelines
- Perform database administration tasks
Prerequisites
- Docker installed and running
- Network access to target MongoDB server
- MongoDB user credentials with appropriate permissions
Configuration
Add to your .skill-engine.toml:
[skills.mongodb]
source = "docker:mongo:7"
runtime = "docker"
description = "MongoDB database client"
[skills.mongodb.docker]
image = "mongo:7"
entrypoint = "mongosh"
network = "bridge"
memory = "256m"
rm = true
Configuration Explained
| Setting | Value | Description |
|---|---|---|
image |
mongo:7 |
Official MongoDB 7 image with mongosh |
entrypoint |
mongosh |
Use the MongoDB Shell client |
network |
bridge |
Bridge network to connect to external databases |
memory |
256m |
Memory limit for the container |
rm |
true |
Auto-remove container after execution |
Usage
Arguments after -- are passed directly to mongosh:
skill run mongodb -- [mongosh options] [connection string] [script]
Common Operations
Connect and Run Query
# Connect to local MongoDB
skill run mongodb -- --eval "db.users.find().limit(5)" mongodb://localhost:27017/mydb
# Connect with authentication
skill run mongodb -- --eval "db.users.find()" "mongodb://user:password@localhost:27017/mydb"
# Connect to replica set
skill run mongodb -- --eval "db.users.countDocuments()" "mongodb://host1,host2,host3/mydb?replicaSet=rs0"
List Databases and Collections
# List all databases
skill run mongodb -- --eval "db.adminCommand('listDatabases')" mongodb://localhost:27017
# List collections in a database
skill run mongodb -- --eval "db.getCollectionNames()" mongodb://localhost:27017/mydb
# Get collection stats
skill run mongodb -- --eval "db.users.stats()" mongodb://localhost:27017/mydb
What ships with it
2 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 is a skill published in the GitHub repository kubiyabot/skill (16 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 12 tokens to every session and 1,951 once invoked, about $0.0001 per session on Opus 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.
