Implementation Reference

• packages/mcp-server/src/index.ts:350-360 (handler)

  The MCP tool handler for 'get_agent_reputation', which calls 'sdk.deep(address)' to retrieve reputation data.

  async ({ address }) => {
    try {
      const data = await sdk.deep(address);
      return {
        content: [
          {
            type: "text" as const,
            text: JSON.stringify(data, null, 2),
          },
        ],
      };

• packages/mcp-server/src/index.ts:342-349 (registration)

  Registration of the 'get_agent_reputation' tool in the MCP server.

  server.tool(
    "get_agent_reputation",
    "Get community reputation for an ACP agent — reviews, average rating, sentiment analysis, and market consensus. Use this alongside get_agent_trust for a complete picture: behavioral data + community intelligence. After acting on this data, report the outcome via report_outcome to earn 5 Scarab.",
    {
      address: z
        .string()
        .describe("Ethereum/Base wallet address (0x...) of the agent"),
    },

• src/lib/erc8004.ts:134-160 (helper)

  The underlying function implementation for fetching agent reputation from the blockchain, although the MCP tool uses a different 'sdk.deep' method for this specific tool name.

  export async function getAgentReputation(
    agentId: bigint
  ): Promise<{ count: number; normalizedScore: number } | null> {
    return withFallback(async (client) => {
      const [reputation, normalizedScore] = await Promise.all([
        client.readContract({
          address: REPUTATION_REGISTRY,
          abi: REPUTATION_ABI,
          functionName: 'getReputation',
          args: [agentId],
        }),
        client.readContract({
          address: REPUTATION_REGISTRY,
          abi: REPUTATION_ABI,
          functionName: 'getReputationNormalized',
          args: [agentId],
        }),
      ])
  
      const [count] = reputation as [bigint, bigint]
  
      return {
        count: Number(count),
        normalizedScore: Number(normalizedScore as bigint),
      }
    })
  }
