| archived | No | ||
| cover | No | A cover image for the page. Only [external file objects](https://developers.notion.com/reference/file-object) are supported. | |
| icon | No | A page icon for the page. Supported types are [external file object](https://developers.notion.com/reference/file-object) or [emoji object](https://developers.notion.com/reference/emoji-object). | |
| in_trash | No | Set to true to delete a block. Set to false to restore a block. | |
| page_id | Yes | The identifier for the Notion page to be updated. | |
| properties | No | The property values to update for the page. The keys are the names or IDs of the property and the values are property values. If a page property ID is not included, then it is not changed. |
Implementation Reference
- The MCP tool execution handler for all dynamically generated tools, including "API-patch-page". It resolves the tool name to the corresponding OpenAPI operation (PATCH /pages/{page_id} for patch-page), executes the HTTP request via HttpClient, and formats the response as MCP content.// Handle tool calling this.server.setRequestHandler(CallToolRequestSchema, async (request) => { const { name, arguments: params } = request.params // Find the operation in OpenAPI spec const operation = this.findOperation(name) if (!operation) { throw new Error(`Method ${name} not found`) } try { // Execute the operation const response = await this.httpClient.executeOperation(operation, params) // Convert response to MCP format return { content: [ { type: 'text', // currently this is the only type that seems to be used by mcp server text: JSON.stringify(response.data), // TODO: pass through the http status code text? }, ], } } catch (error) { console.error('Error in tool call', error) if (error instanceof HttpClientError) { console.error('HttpClientError encountered, returning structured error', error) const data = error.data?.response?.data ?? error.data ?? {} return { content: [ { type: 'text', text: JSON.stringify({ status: 'error', // TODO: get this from http status code? ...(typeof data === 'object' ? data : { data: data }), }), }, ], } } throw error } })
- src/openapi-mcp-server/mcp/proxy.ts:57-75 (registration)Registers the listTools request handler which dynamically constructs and returns the list of available tools. Constructs tool names as 'API-{operationId}' (e.g. 'API-patch-page') from the OpenAPI spec converter output.// Handle tool listing this.server.setRequestHandler(ListToolsRequestSchema, async () => { const tools: Tool[] = [] // Add methods as separate tools to match the MCP format Object.entries(this.tools).forEach(([toolName, def]) => { def.methods.forEach(method => { const toolNameWithMethod = `${toolName}-${method.name}`; const truncatedToolName = this.truncateToolName(toolNameWithMethod); tools.push({ name: truncatedToolName, description: method.description, inputSchema: method.inputSchema as Tool['inputSchema'], }) }) }) return { tools } })
- Generates the input schemas and tool metadata for all MCP tools from the OpenAPI document. The tool 'API-patch-page' is created here when processing the operation with operationId 'patch-page', deriving inputSchema from parameters and requestBody.convertToMCPTools(): { tools: Record<string, { methods: NewToolMethod[] }> openApiLookup: Record<string, OpenAPIV3.OperationObject & { method: string; path: string }> zip: Record<string, { openApi: OpenAPIV3.OperationObject & { method: string; path: string }; mcp: NewToolMethod }> } { const apiName = 'API' const openApiLookup: Record<string, OpenAPIV3.OperationObject & { method: string; path: string }> = {} const tools: Record<string, { methods: NewToolMethod[] }> = { [apiName]: { methods: [] }, } const zip: Record<string, { openApi: OpenAPIV3.OperationObject & { method: string; path: string }; mcp: NewToolMethod }> = {} for (const [path, pathItem] of Object.entries(this.openApiSpec.paths || {})) { if (!pathItem) continue for (const [method, operation] of Object.entries(pathItem)) { if (!this.isOperation(method, operation)) continue const mcpMethod = this.convertOperationToMCPMethod(operation, method, path) if (mcpMethod) { const uniqueName = this.ensureUniqueName(mcpMethod.name) mcpMethod.name = uniqueName mcpMethod.description = this.getDescription(operation.summary || operation.description || '') tools[apiName]!.methods.push(mcpMethod) openApiLookup[apiName + '-' + uniqueName] = { ...operation, method, path } zip[apiName + '-' + uniqueName] = { openApi: { ...operation, method, path }, mcp: mcpMethod } } } } return { tools, openApiLookup, zip } }
- Helper method that maps tool name (e.g. 'API-patch-page') to the corresponding OpenAPI operation object for execution.private findOperation(operationId: string): (OpenAPIV3.OperationObject & { method: string; path: string }) | null { return this.openApiLookup[operationId] ?? null }
