@openpresentation/mcp

The MCP server for OPF (Open Presentation Format). An agent or editor that speaks the Model Context Protocol learns the format and checks decks through it, without shelling out and parsing text: documentation, schemas, the default catalog, example decks and the six agent skills as resources, a start_here tool that gives a path for a goal, and validate_deck, get_schema, search_catalog, get_catalog_record, convert, search_docs and list_examples as tools. It keeps no state, reads no file, fetches nothing, and needs no API key. Node 22 or later.

claude mcp add opf -- npx -y @openpresentation/mcp          # Claude Code
npx -y @openpresentation/mcp                                  # any MCP client: command npx, args -y @openpresentation/mcp

Tools, resources (opf://docs/format-card, opf://schema/presentation#Chart, opf://catalog/layouts/two-column, ...), prompts, client setup (Claude Code, Cursor, Claude Desktop) and a typical session: the MCP server.

As a library

The server definition is separate from the transport and runs on an edge runtime (no Node builtin, no file read, precompiled validators), for a hosted server:

import { createOpfServer } from "@openpresentation/mcp";           // with the bundled docs, examples, skills and release notes
import { createOpfMcpServer } from "@openpresentation/mcp/server"; // the same without that data: you pass `sources`

const server = createOpfServer({ version: "0.27.0" });
await server.connect(transport); // stdio, or Streamable HTTP in a Worker

@openpresentation/mcp/stdio is the Node stdio wrapper (runStdio()) that the opf-mcp binary and opf mcp of the CLI run. Layout is measured with the real fonts when the optional peer @openpresentation/opf-render is installed beside it; otherwise it is estimated and the report says so. The package is released with @openpresentation/opf and the other packages of OpenPresentation/opf at one version.
