01 · Install Inquisitor

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add 1111111111111111111114olvt2-inquisitor -- uvx inquisitor-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "1111111111111111111114olvt2-inquisitor": {
      "command": "uvx",
      "args": [
        "inquisitor-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-07 - young repo, little track record yet

license MIT - declared in the repository

pypi package inquisitor-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.1111111111111111111114oLvT2 is GitHub-verified and matches the repo owner

03 · What Inquisitor can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

An agent gets 5 documented tools, including inquisitor_search, inquisitor_analyze, inquisitor_trace, inquisitor_verify, inquisitor_scaffold.

The 5 tools it gives your agent

Extracted from the project's README - what inquisitor lets an agent do.

inquisitor_search: - Multi-backend web search (DuckDuckGo free/keyless, Brave, SearXNG) with content extraction (HTML + PDF)
inquisitor_analyze: - Project overview: languages, frameworks, tests, deps, git history
inquisitor_trace: - Symbol tracing: definition, callers, callees with file:line refs
inquisitor_verify: - Completeness check: every phase recorded? evidence cited? (semantic validation - contradictions, DEFINE satisfaction - stays with the agent)
inquisitor_scaffold: - Minimal project scaffolding with researched best practices
