Implementation Reference

• src/tool_handlers.ts:334-352 (handler)

  Implements the core logic for the w3_proof_add tool: validates input arguments using the schema, runs the 'w3 proof add' CLI command with the proofPath, and formats the stdout output into a MCP response.

  const handleW3ProofAdd: ToolHandler = async (args) => {
    const parsed = Schemas.W3ProofAddArgsSchema.safeParse(args);
    if (!parsed.success)
      throw new Error(
        `Invalid arguments for w3_proof_add: ${parsed.error.message}`
      );
    const { proofPath } = parsed.data;
    const { stdout } = await runW3Command(`proof add "${proofPath}"`);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            message: `Successfully added proof from ${proofPath}.`,
            output: stdout.trim(),
          }),
        },
      ],
    };

• src/schemas.ts:143-149 (schema)

  Defines the Zod input validation schema for w3_proof_add, requiring a single 'proofPath' string parameter describing the absolute path to the proof file.

  export const W3ProofAddArgsSchema = z.object({
    proofPath: z
      .string()
      .describe(
        "ABSOLUTE path to the CAR encoded proof file delegated to this agent."
      ),
  });

• src/tool_handlers.ts:944-980 (registration)

  Registers the 'w3_proof_add' tool by mapping its name to the handleW3ProofAdd handler function in the exported toolHandlers object, which is used by the MCP server to dispatch tool calls.

  export const toolHandlers: Record<string, ToolHandler> = {
    w3_login: handleW3Login,
    w3_space_ls: handleW3SpaceLs,
    w3_space_use: handleW3SpaceUse,
