We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.
mc-mcp is an extensible MCP server for the metacontract (mc) framework. It enables AI-powered smart contract development workflows via Foundry integration and semantic documentation search, exposing tools for project setup, testing, deployment, and documentation retrieval.
Install via cargo install mc-mcp, add the server to your MCP client (e.g., Cursor, Cline, RooCode) with MC_PROJECT_ROOT set to your project directory. The server automatically starts and provides tools like mc_search_docs_semantic, mc_setup, mc_test, mc_deploy, and mc_upgrade. An optional mcp_config.toml file under the project root customizes reference sources and script paths.
mc_test via your agentmcp_config.toml`MC_PROJECT_ROOT` is an environment variable specifying the project root directory. It is required because path resolution is delegated to the MCP client, ensuring consistent behavior across environments. If unset or non-existent, the server returns an error.
Place a `mcp_config.toml` file in your `MC_PROJECT_ROOT` directory. It defines documentation sources (local paths) and default Foundry scripts for deploy/upgrade. If the file is missing, mc-mcp uses built-in defaults.
mc-mcp uses stdio transport (as shown in client configurations). No authentication mechanism is documented.
On first startup, the prebuilt documentation index (`prebuilt_index.jsonl.gz`) is downloaded from the latest GitHub Release and cached in the system cache directory. The path can be overridden in `mcp_config.toml` via `prebuilt_index_path`.
The server requires Rust, Foundry (for test/deploy tools), and an MCP-compatible client. Tests may hit OS file descriptor limits (`ulimit -n 4096` recommended) or embedding model cache lock errors—these can be resolved with `make clean-cache` and single-threaded test execution.
