scrybe-mcp-server 0.4.0

Scrybe MCP server — standalone inbound MCP server (binary wheel)

scrybe-mcp-server

Inbound MCP server: exposes Scrybe's editing capabilities as MCP tools that external agents (Claude Code, Codex, custom agents) can call. Python on the outside, Rust on the inside.

What it does

Implements the MCP JSON-RPC 2.0 protocol over stdio. An AI agent connects to this process and gains structured, safe access to open Markdown documents — reading, editing, searching, rendering, and managing the running app — without direct filesystem access.

Role in the architecture

scrybe-mcp-server is the agent-facing surface of Scrybe. It holds an in-memory Workspace (from scrybe-core) and coordinates with scrybe-render and scrybe-mermaid to serve tool calls. The Tauri app launches it as a sidecar process. Agents connect via:

claude mcp add scrybe -- scrybe-mcp-server stdio

Exposed tools (12)

Build and test

cargo build -p scrybe-mcp-server
cargo test -p scrybe-mcp-server

# Install the binary
cargo install --path .

The binary (scrybe-mcp-server) speaks MCP over stdio. Add it to any MCP client's server list with transport stdio.
