Implementation Reference
- The core handler function for the 'get-latest-prompt' tool. It uses the PhoenixClient to fetch the latest version of the specified prompt via the API endpoint "/v1/prompts/{prompt_identifier}/latest" and returns the response data as formatted JSON text.
async ({ prompt_identifier }) => { const response = await client.GET( "/v1/prompts/{prompt_identifier}/latest", { params: { path: { prompt_identifier, }, }, } ); return { content: [ { type: "text", text: JSON.stringify(response.data, null, 2), }, ], }; } - js/packages/phoenix-mcp/src/promptTools.ts:273-296 (registration)Registers the 'get-latest-prompt' tool on the MCP server, providing the name, description, input schema, and handler function.
"get-latest-prompt", GET_LATEST_PROMPT_DESCRIPTION, getLatestPromptSchema.shape, async ({ prompt_identifier }) => { const response = await client.GET( "/v1/prompts/{prompt_identifier}/latest", { params: { path: { prompt_identifier, }, }, } ); return { content: [ { type: "text", text: JSON.stringify(response.data, null, 2), }, ], }; } ); - Zod schema defining the input for the tool: requires a 'prompt_identifier' string (name or ID of the prompt).
export const getLatestPromptSchema = z.object({ prompt_identifier: z.string(), }); - js/packages/phoenix-mcp/src/index.ts:40-40 (registration)Calls the initialization function that registers the prompt tools, including 'get-latest-prompt', on the MCP server instance.
