mavis_session_abort

Instructions

Implementation Reference

• src/index.js:32-53 (handler)

  The execMavis function is the actual handler that spawns the mavis CLI process with the args built by mavis_session_abort's buildArgs. It runs 'mavis session abort <sessionId>' and returns the raw stdout output.

  function execMavis(args, input = '') {
    return new Promise((resolve, reject) => {
      const SESSION_COMMANDS = new Set(['communication', 'session', 'spawn']);
      const sessionId = process.env.__MAVIS_PARENT_SESSION_ID;
      const subcmd = args[0];
      const needsSession = SESSION_COMMANDS.has(subcmd) && sessionId;
      const finalArgs = needsSession ? [...args, '--session', sessionId] : args;
      const proc = spawn(MAVIS_BIN, finalArgs, { stdio: ['pipe', 'pipe', 'pipe'] });
      let stdout = '';
      let stderr = '';
  
      proc.stdout.on('data', d => stdout += d.toString());
      proc.stderr.on('data', d => stderr += d.toString());
      proc.on('close', code => {
        if (code === 0) resolve(stdout.trim());
        else reject(new Error(stderr.split('\n')[0] || `exit code ${code}`));
      });
      proc.on('error', reject);
  
      if (input) proc.stdin.write(input), proc.stdin.end();
    });
  }

• src/index.js:164-166 (schema)

  Input schema for mavis_session_abort: requires a single string field 'sessionId'.

  inputSchema: z.object({
    sessionId: z.string().describe('Session ID to abort')
  }),

• src/index.js:161-170 (registration)

  Tool registration for mavis_session_abort. It's defined as an entry in the 'tools' array with 'execFn: execMavis', 'outputMode: OUTPUT_RAW', and a buildArgs function that constructs ['session', 'abort', sessionId].

  {
    name: 'mavis_session_abort',
    description: 'Abort a running session.',
    inputSchema: z.object({
      sessionId: z.string().describe('Session ID to abort')
    }),
    execFn: execMavis,
    outputMode: OUTPUT_RAW,
    buildArgs: ({ sessionId }) => ['session', 'abort', sessionId]
  },

• src/index.js:77-92 (helper)

  The runTool helper orchestrates tool execution. It calls buildArgs to get the CLI args, then invokes execMavis (since mavis_session_abort specifies execFn), and returns the raw output string.

  function runTool(spec, parsedArgs) {
    const { execFn, outputMode, stdin, buildArgs } = spec;
    const args = buildArgs(parsedArgs);
    const input = typeof stdin === 'function' ? stdin(parsedArgs) : stdin;
  
    const execPromise = execFn
      ? execMavis(args, input || '')
      : execMavisJSON(args);
  
    return execPromise.then(result => {
      const text = outputMode === OUTPUT_RAW
        ? (result || '')
        : JSON.stringify(result, null, 2);
      return [{ type: 'text', text }];
    });
  }
