Implementation Reference

• packages/mcp/src/tools/safety.ts:15-58 (handler)

  Handler logic for the t2000_config tool, which handles both 'show' and 'set' actions to view or update safeguard limits.

  async ({ action, key, value }) => {
    try {
      if (action === 'show') {
        const config = agent.enforcer.getConfig();
        return {
          content: [{
            type: 'text',
            text: JSON.stringify({
              locked: config.locked,
              maxPerTx: config.maxPerTx,
              maxDailySend: config.maxDailySend,
              dailyUsed: config.dailyUsed,
            }),
          }],
        };
      }
  
      if (!key || value === undefined) {
        return errorResult(new Error('Both "key" and "value" are required for action "set"'));
      }
  
      if (key === 'locked') {
        return errorResult(new Error('Cannot set "locked" via config. Use t2000_lock to freeze operations.'));
      }
  
      if (key !== 'maxPerTx' && key !== 'maxDailySend') {
        return errorResult(new Error(`Unknown key "${key}". Valid keys: "maxPerTx", "maxDailySend"`));
      }
  
      if (value < 0) {
        return errorResult(new Error('Value must be a non-negative number'));
      }
  
      agent.enforcer.set(key, value);
      return {
        content: [{
          type: 'text',
          text: JSON.stringify({ updated: true, key, value }),
        }],
      };
    } catch (err) {
      return errorResult(err);
    }
  },

• packages/mcp/src/tools/safety.ts:10-14 (schema)

  Zod schema definition for input arguments of t2000_config.

  {
    action: z.enum(['show', 'set']).describe('"show" to view current limits, "set" to update a limit'),
    key: z.string().optional().describe('Setting to update: "maxPerTx" or "maxDailySend"'),
    value: z.number().optional().describe('New value in dollars (0 = unlimited)'),
  },

• packages/mcp/src/tools/safety.ts:7-9 (registration)

  Registration of the t2000_config tool within the MCP server.

  server.tool(
    't2000_config',
    'View or set agent safeguard limits (per-transaction max, daily send limit). Use action "show" to view current limits, "set" to update. Values are in dollars. Set to 0 for unlimited.',
