Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| rpc_call | Call any JSON-RPC method on a server with parameters. A user would prompt: Call method <method> on <server url> with params <params> |
| rpc_discover | This uses JSON-RPC to call `rpc.discover` which is part of the OpenRPC Specification for discovery for JSON-RPC servers. A user would prompt: What JSON-RPC methods does this server have? <server url> |

Installation
To use with Claude Desktop, add the server config:
On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json
Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector:
The Inspector will provide a URL to access debugging tools in your browser.
GitHub Badge
Glama performs regular codebase and documentation scans to:
- Confirm that the MCP server is working as expected.
- Confirm that there are no obvious security issues with dependencies of the server.
- Extract server characteristics such as tools, resources, prompts, and required parameters.
Our directory badge helps users to quickly asses that the MCP server is safe, server capabilities, and instructions for installing the server.
