request_intro

Instructions

Implementation Reference

• src/index.ts:207-238 (handler)

  Handler function that executes the request_intro tool logic. Makes POST request to /api/intros endpoint with match details, agent credentials, and cryptographic signature. Returns intro ID and pending status on success, or error message on failure.

  async (args) => {
    try {
      const result = await api("/api/intros", {
        method: "POST",
        body: JSON.stringify({
          matchId: args.match_id,
          targetAgentId: args.to,
          message: args.message,
          fieldsToDisclose: ["needs", "offers"],
          agentId,
          publicKey: keys.publicKey,
          signature: sign(args.match_id + args.message, keys.privateKey),
        }),
      });
  
      if (result.error) return { content: [{ type: "text" as const, text: `Failed: ${result.error}` }], isError: true };
  
      return {
        content: [{
          type: "text" as const,
          text: JSON.stringify({
            introId: result.introId,
            status: "pending",
            to: args.to,
            note: "Intro request sent. They'll see it in their digest.",
          }, null, 2),
        }],
      };
    } catch (e: any) {
      return { content: [{ type: "text" as const, text: `Network error: ${e.message}` }], isError: true };
    }
  }

• src/index.ts:202-206 (schema)

  Input schema defining three required string parameters: match_id (from search results), to (target agent ID), and message (explanation for the intro).

  {
    match_id: z.string().describe("Match ID from search_matches"),
    to: z.string().describe("Agent ID of the person you want to meet"),
    message: z.string().describe("Short message explaining why this intro would be valuable"),
  },

• src/index.ts:199-239 (registration)

  Complete tool registration calling server.tool() with name 'request_intro', description, input schema, and handler function. Registers the tool with the MCP server.

  server.tool(
    "request_intro",
    "Propose an introduction to someone you matched with. They'll see your message and can approve or decline. Nothing happens without both sides saying yes.",
    {
      match_id: z.string().describe("Match ID from search_matches"),
      to: z.string().describe("Agent ID of the person you want to meet"),
      message: z.string().describe("Short message explaining why this intro would be valuable"),
    },
    async (args) => {
      try {
        const result = await api("/api/intros", {
          method: "POST",
          body: JSON.stringify({
            matchId: args.match_id,
            targetAgentId: args.to,
            message: args.message,
            fieldsToDisclose: ["needs", "offers"],
            agentId,
            publicKey: keys.publicKey,
            signature: sign(args.match_id + args.message, keys.privateKey),
          }),
        });
  
        if (result.error) return { content: [{ type: "text" as const, text: `Failed: ${result.error}` }], isError: true };
  
        return {
          content: [{
            type: "text" as const,
            text: JSON.stringify({
              introId: result.introId,
              status: "pending",
              to: args.to,
              note: "Intro request sent. They'll see it in their digest.",
            }, null, 2),
          }],
        };
      } catch (e: any) {
        return { content: [{ type: "text" as const, text: `Network error: ${e.message}` }], isError: true };
      }
    }
  );

• src/index.ts:19-30 (helper)

  Helper function that wraps fetch API calls with required headers including agent ID and public key for authentication. Used by the request_intro handler to communicate with the backend API.

  async function api(path: string, opts?: RequestInit): Promise<any> {
    const res = await fetch(`${API}${path}`, {
      ...opts,
      headers: {
        "Content-Type": "application/json",
        "X-Agent-Id": agentId,
        "X-Public-Key": keys.publicKey,
        ...opts?.headers,
      },
    });
    return res.json();
  }
