Ten environmental layers at one point on Earth in a single call: weather, air quality and pollen, sea state, aviation, space weather, hazards, earthquakes, radiation, official warnings, and whether today is unusual for the date. Fifteen sources, no API key.

Search nine scholarly sources in one call, screen any paper for retractions before you cite it, find a legal free copy, walk citation graphs, and track a question so you only ever see what is new. No API key.

Audits package.json for typosquatting risk against the most-depended-on npm packages, malicious install-script patterns (curl-pipe-shell, obfuscated base64 payloads), and unpinned dependency versions.

Audits MCP tool definitions for documented tool-poisoning and tool-shadowing attack patterns -- hidden agent-directed instructions in descriptions, sensitive-path references, invisible/homoglyph Unicode in tool names, and near-duplicate tool names.

Scans text and git diffs for accidentally-committed credentials via high-precision structural matching against real current key formats (AWS, GitHub, Stripe, Slack, Google, OpenAI, Anthropic, npm, SendGrid, Twilio, PEM keys, JWTs, DB connection strings) plus an entropy-based fallback for unrecognized secret-shaped values.

Audits Dockerfiles for missing USER instructions, credentials baked into ENV/ARG, curl-pipe-shell patterns, unpinned :latest base images, and remote-URL ADD instructions. Handles multi-stage builds correctly (only the final shipped stage's USER matters).

Audits GitHub Actions workflow YAML for script injection via untrusted event-context expressions interpolated into shell steps, third-party actions pinned to a mutable tag/branch instead of a commit SHA, missing permissions blocks, and pull_request_target combined with checking out the PR's own head commit.

Ambee mcp server

FREEMIUM

An MCP server that gives AI assistants live access to weather, pollen, and air quality data for any location worldwide, powered by Ambee. Ask about current conditions or a 48-hour outlook — temperature, humidity, wind, UV index, pollen risk by type (tree/weed/grass), or AQI and pollutant breakdown — for a city, address, postcode, or raw coordinates. The server resolves free-text locations automatically, so no separate geocoding step is needed.
