Implementation Reference
- src/tools/builtin/select_site.ts:17-35 (handler)The handler function that executes the tool logic: validates the site URL by fetching /about.json, selects the site in state, optionally registers remote tools, and returns success or error message.
async ({ site }, _extra: any) => { try { const { base, client } = ctx.siteState.buildClientForSite(site); // Validate by fetching /about.json const about = (await client.get(`/about.json`)) as any; const title = about?.about?.title || about?.title || base; ctx.siteState.selectSite(base); // Attempt remote tool discovery if enabled if (opts.toolsMode && opts.toolsMode !== "discourse_api_only") { await tryRegisterRemoteTools(server, ctx.siteState, ctx.logger); } const text = `Selected site: ${base}\nTitle: ${title}`; return { content: [{ type: "text", text }] }; } catch (e: any) { return { content: [{ type: "text", text: `Failed to select site: ${e?.message || String(e)}` }], isError: true }; } } - src/tools/builtin/select_site.ts:6-8 (schema)Zod schema defining the input: a URL string for the Discourse site.
const schema = z.object({ site: z.string().url().describe("Base URL of the Discourse site"), }); - src/tools/builtin/select_site.ts:10-36 (registration)Registration of the 'discourse_select_site' tool with the MCP server, including title, description, input schema, and handler.
server.registerTool( "discourse_select_site", { title: "Select Site", description: "Validate and select a Discourse site for subsequent tool calls.", inputSchema: schema.shape, }, async ({ site }, _extra: any) => { try { const { base, client } = ctx.siteState.buildClientForSite(site); // Validate by fetching /about.json const about = (await client.get(`/about.json`)) as any; const title = about?.about?.title || about?.title || base; ctx.siteState.selectSite(base); // Attempt remote tool discovery if enabled if (opts.toolsMode && opts.toolsMode !== "discourse_api_only") { await tryRegisterRemoteTools(server, ctx.siteState, ctx.logger); } const text = `Selected site: ${base}\nTitle: ${title}`; return { content: [{ type: "text", text }] }; } catch (e: any) { return { content: [{ type: "text", text: `Failed to select site: ${e?.message || String(e)}` }], isError: true }; } } ); - src/tools/registry.ts:37-39 (registration)Top-level call to register the select_site tools, conditional on hideSelectSite option.
if (!opts.hideSelectSite) { registerSelectSite(server, ctx, { allowWrites: false, toolsMode: opts.toolsMode }); }
