It calls the FutarchyApiClient.sellInFailMarket method and formats the response as MCP content or error.async ({ proposalId, amount, user }) => { try { const response = await apiClient.sellInFailMarket(proposalId, amount, user); if (!response.success) { return { content: [ { type: "text" as const, text: response.error || 'Unknown error', }, ], isError: true, }; } return { content: [ { type: "text" as const, text: JSON.stringify(response.data, null, 2), }, ], }; } catch (error: any) { return { content: [ { type: "text" as const, text: `Error selling in fail market: ${error.message || 'Unknown error'}`, }, ], isError: true, }; } }
- src/mcp/server/index.ts:466-510 (registration)The registration of the sellInFailMarket tool on the MCP server, including name, description, input schema, and handler reference.server.tool( "sellInFailMarket", "Sell tokens in the fail market for a proposal", { proposalId: z.string().describe("The ID of the proposal to trade in"), amount: z.number().describe("Amount to sell"), user: z.string().describe("User's public key"), }, async ({ proposalId, amount, user }) => { try { const response = await apiClient.sellInFailMarket(proposalId, amount, user); if (!response.success) { return { content: [ { type: "text" as const, text: response.error || 'Unknown error', }, ], isError: true, }; } return { content: [ { type: "text" as const, text: JSON.stringify(response.data, null, 2), }, ], }; } catch (error: any) { return { content: [ { type: "text" as const, text: `Error selling in fail market: ${error.message || 'Unknown error'}`, }, ], isError: true, }; } } );
- src/mcp/server/index.ts:469-473 (schema)Zod input schema for the sellInFailMarket tool parameters.{ proposalId: z.string().describe("The ID of the proposal to trade in"), amount: z.number().describe("Amount to sell"), user: z.string().describe("User's public key"), },
- src/mcp/common/api.ts:254-282 (helper)Helper function in FutarchyApiClient that makes HTTP POST request to the backend API to sell tokens in the fail market.async sellInFailMarket(proposalId: string, amount: number, userPublicKey: string): Promise<Response> { try { const response = await fetch(`${this.baseUrl}/proposals/${proposalId}/sell-fail`, { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ amount, user: userPublicKey }) }); if (!response.ok) { throw new Error(`HTTP error! Status: ${response.status}`); } const data = await response.json(); return { success: true, data: data }; } catch (error: any) { return { success: false, error: error.message || 'Failed to sell in fail market' }; } }
