Implementation Reference
- src/index.ts:335-351 (handler)MCP tool handler that executes search_chains by calling ChainLookupService.searchChains with the provided query and formats the results as text response.
case "search_chains": const searchResults = await this.chainLookupService.searchChains( args.query as string ); return { content: [ { type: "text", text: searchResults.length > 0 ? `Found chains:\n${searchResults .map((c) => `${c.name} (ID: ${c.chainId})`) .join("\n")}` : `No chains found matching "${args.query}"`, }, ], }; - src/index.ts:1048-1062 (schema)Input schema and metadata definition for the search_chains tool, specifying the required 'query' parameter.
