Frame Check MCP server: deterministic structural framing analysis for AI-generated documents, with default-on frame-divergence block per FRAME_DIVERGENCE_CONTRACT_v1 c1.0. MCP surface delegates V4.2 judgment to the caller's agent model; zero Frame Check LLM cost per query.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"frame-check-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# Frame Check [](https://pypi.org/project/frame-check-mcp/) [](https://pypi.org/project/frame-check-mcp/) [](https://www.apache.org/licenses/LICENSE-2.0) [](https://github.com/lluvr/frame-check/actions/workflows/tests.yml) See what any document does not show you. Frame Check is a deterministic structural framing analysis tool. It names which analytical perspectives a document takes, which it omits, and how it positions the reader, and it cross-checks the document's numeric claims against primary sources a language model can't reach (SEC EDGAR, FRED, World Bank, and others). It makes no LLM call of its own, so the same document always returns the same reading at no model cost. ## Quickstart (MCP server) The PyPI package `frame-check-mcp` is the Model Context Protocol server. It runs locally and gives any MCP-compatible AI client (Claude Desktop, Cursor, Cline, Continue.dev, etc.) deterministic structural framing analysis as a tool. pip install frame-check-mcp Then point your MCP client at the installed entry point. For Claude Desktop, add to `claude_desktop_config.json`: { "mcpServers": { "frame-check": { "command": "frame-check-mcp" } } } Restart the client. Then in any conversation: "Can you frame-check this document?" Full install + verification details in `docs/MCP_SERVER.md`. ### Verifying the wheel (sigstore attestation) Every published wheel ships with a sigstore build-provenance attestation generated inside the GitHub Actions publish workflow via OIDC. Adopters who want to verify the wheel was built from this repository's CI (and not modified between the runner and PyPI) can do so with the `gh` CLI: pip download frame-…
