Crate rlg_mcp 

MCP (Model Context Protocol) tool implementations and the minimal JSON-RPC 2.0 dispatcher that wires them to a Server.

The wire format follows the MCP specification’s stdio transport: one JSON-RPC request per line on stdin, one response per line on stdout.

The three tools (tail_log, filter_log, summarize_errors) are pure functions over a file path so they can be unit-tested without spinning up the transport loop.

Example

use std::path::Path;
let recent = rlg_mcp::tail_log(Path::new("/var/log/app.ndjson"), 10).unwrap();
for line in recent { println!("{line}"); }

Structs

Request

JSON-RPC 2.0 request envelope.

Response

JSON-RPC 2.0 response envelope.

ResponseError

JSON-RPC 2.0 error object.

Functions

dispatch

Dispatch one JSON-RPC request to the appropriate handler.

filter_log

Apply filter to every record in path and return matches rendered in format.

summarize_errors

Count error+ records grouped by component.

tail_log

Return the last n parseable records from path, rendered in Logfmt. Unparseable lines are skipped.
