Implementation Reference

• src/tool_handlers.ts:812-831 (handler)

  The main handler function that executes the w3_can_access_claim tool logic. It parses the input arguments using the schema, executes the w3 CLI command 'can access claim', and returns the output in the expected format.

  const handleW3CanAccessClaim: ToolHandler = async (args) => {
    const parsed = Schemas.W3CanAccessClaimArgsSchema.safeParse(args);
    if (!parsed.success)
      throw new Error(
        `Invalid arguments for w3_can_access_claim: ${parsed.error.message}`
      );
    const { proof } = parsed.data;
    const { stdout } = await runW3Command(`can access claim "${proof}"`);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            message: "Capability claim attempted.",
            output: stdout.trim(),
          }),
        },
      ],
    };
  };

• src/schemas.ts:339-349 (schema)

  Zod schema defining the input arguments for the w3_can_access_claim tool, specifically requiring a 'proof' string.

  export const W3CanAccessClaimArgsSchema = z
    .object({
      proof: z
        .string()
        .describe(
          "Delegation proof (e.g., path to CAR file or base64 CID string) containing capabilities to claim."
        ),
    })
    .describe(
      "Claims delegated capabilities for the authorized account using a provided proof."
    );

• src/tool_handlers.ts:974-974 (registration)

  Registration of the 'w3_can_access_claim' tool name mapped to its handler function in the toolHandlers export.

  w3_can_access_claim: handleW3CanAccessClaim,
