Implementation Reference
- src/tools.ts:98-172 (handler)The core handler function that implements the 'get_marinade_state' tool. It instantiates Marinade, calls getMarinadeState(), serializes the result handling Solana-specific types (PublicKey, BN), circular refs, and returns formatted JSON or error.
callback: async () => { try { const marinade = new Marinade() const marinadeStateRaw = await marinade.getMarinadeState(); const visited = new WeakSet(); const marinadeState = JSON.parse(JSON.stringify(marinadeStateRaw, (key, value) => { if (value === null || typeof value !== 'object') { return value; } if (visited.has(value)) { return '[Circular Reference]'; } visited.add(value); if (value && value.constructor?.name === 'PublicKey') { return value.toString(); } if (value && value.constructor?.name === 'BN') { return value.toString(); } const problematicTypes = [ 'Marinade', 'MarinadeReferralProgram', 'RpcWebSocketClient', 'Connection', 'EventEmitter', 'Events' ]; if (value.constructor && problematicTypes.includes(value.constructor.name)) { return '[Filtered Object: ' + value.constructor.name + ']'; } if (typeof value === 'function' || (value && value._events)) { return undefined; } return value; })); return { content: [ { type: "text", text: JSON.stringify(marinadeState, null, 2), }, ], }; } catch (err) { const isAbort = (err as Error)?.name === "AbortError"; return { content: [ { type: "text", text: JSON.stringify( { error: isAbort ? "Request timed out" : "Failed to fetch Marinade State", reason: String((err as Error)?.message ?? err), }, null, 2 ), }, ], }; } } - src/tools.ts:97-97 (schema)The input schema for the tool, defined as an empty object since the tool requires no input parameters.
inputSchema: {}, - src/server.ts:25-43 (registration)Registers all tools from marinadeFinanceTools (including get_marinade_state) with the MCP server using server.registerTool, passing name, schema/details, and a wrapper around the tool's callback.
for (const t of marinadeFinanceTools) { server.registerTool( t.name, { title: t.title, description: t.description, inputSchema: t.inputSchema }, async (args) => { const result = await t.callback(args); return { content: result.content.map(item => ({ ...item, type: "text" as const })) }; } ); }
