Public data,
answered in one call.

Wisco Labs collects official public data, keeps every version of it, and answers the questions AI agents actually ask. One API, one MCP server, no scraping.

Why agents use it instead of searching

01 · Collected

From the official source, on a schedule

Package registries, OSV and government data with terms that allow reuse, credited on every answer.

02 · Kept

Every version, forever

Most sources only show the current state. We keep the history, so "what changed" and "since when" have answers.

03 · Answered

One call instead of fifty

Cleaned, joined and ranked, as JSON built for a model to read. HTTP API or MCP tool.

One line to connect

Works in Claude Code, Claude, Cursor, VS Code and any MCP client. Listed in the official MCP Registry as dev.wiscolabs/developer-tools.

Run this once in a terminal. Claude Code will offer the tools whenever you work on a Python or JavaScript project.

claude mcp add --transport http wisco-labs https://api.wiscolabs.dev/mcp

Add this to .cursor/mcp.json in your project, or to ~/.cursor/mcp.json for every project.

{
  "mcpServers": {
    "wisco-labs": { "url": "https://api.wiscolabs.dev/mcp" }
  }
}

For Copilot agent mode: add this to .vscode/mcp.json in your project.

{
  "servers": {
    "wisco-labs": { "type": "http", "url": "https://api.wiscolabs.dev/mcp" }
  }
}

Plain HTTP works too. Every tool accepts GET with query parameters or POST with JSON.

curl -X POST https://api.wiscolabs.dev/v1/package_changes/upgrade_check \
  -H "content-type: application/json" \
  -d '{"requirements": "flask==2.3.3\nrequests==2.31.0"}'

# npm: send package-lock.json as the requirements text
curl -X POST https://api.wiscolabs.dev/v1/package_changes/upgrade_check \
  -H "content-type: application/json" \
  -d "{\"requirements\": $(jq -Rs . package-lock.json)}"

Agents can discover everything on their own from these.

https://api.wiscolabs.dev/llms.txt        what's here, in plain text
https://api.wiscolabs.dev/v1/catalog      every dataset, query and parameter
https://api.wiscolabs.dev/openapi.json    OpenAPI schema
https://api.wiscolabs.dev/mcp             MCP endpoint (streamable HTTP)

Then make it automatic

Agents only call a tool when they think of it. Paste this into your project's CLAUDE.md, AGENTS.md or Cursor rules, and the check happens every time a dependency changes.

## Dependencies
Before adding, upgrading or pinning any Python or npm dependency, check it with the
wisco-labs tools: upgrade_check for the whole requirements.txt or package-lock.json,
what_changed for a single package. Never install a version they report as vulnerable
or malicious; use the suggested version instead. Tell me about any breaking changes
or removals before upgrading.

Free while in beta

No key, no sign-up, no card. Use it in your own projects and your agents' work as much as you reasonably need. Paid plans for heavy use will come later, and we'll post them here well before anything changes.
