Ashby MCP Server

Instructions

Implementation Reference

• src/ashby/server.py:407-434 (handler)

  The handle_call_tool function is the handler that executes all tools defined in the server, including candidate_list_notes, by routing to the appropriate Ashby API endpoint using the TOOL_ENDPOINT_MAP.

  @server.call_tool()
  async def handle_call_tool(name: str, arguments: dict[str, Any]) -> list[types.TextContent]:
      """Route tool calls to the correct Ashby endpoint, passing arguments directly."""
      endpoint = TOOL_ENDPOINT_MAP.get(name)
      if not endpoint:
          return [types.TextContent(type="text", text=f"Unknown tool: {name}")]
  
      try:
          # Pass arguments straight through -- tool schemas already use Ashby's
          # camelCase param names so no translation is needed.
          response = ashby.post(endpoint, data=arguments if arguments else None)
          return [types.TextContent(type="text", text=json.dumps(response, indent=2))]
      except requests.exceptions.HTTPError as e:
          error_body = ""
          if e.response is not None:
              try:
                  error_body = e.response.text
              except Exception:
                  pass
          return [
              types.TextContent(
                  type="text",
                  text=f"Ashby API error on {endpoint}: {e}\n{error_body}",
              )
          ]
      except Exception as e:
          return [types.TextContent(type="text", text=f"Error calling {endpoint}: {e}")]

• src/ashby/server.py:177-189 (schema)

  The candidate_list_notes tool is defined and registered in the TOOLS list, including its input schema.

  types.Tool(
      name="candidate_list_notes",
      description="List all notes for a candidate.",
      inputSchema={
          "type": "object",
          "properties": {
              "candidateId": {"type": "string", "description": "The candidate ID"},
              "limit": {"type": "integer", "description": "Max results per page"},
              "cursor": {"type": "string", "description": "Cursor for next page"},
          },
          "required": ["candidateId"],
      },
  ),

• src/ashby/server.py:374-399 (helper)

  The TOOL_ENDPOINT_MAP maps the candidate_list_notes tool name to the actual API endpoint '/candidate.listNotes'.

  TOOL_ENDPOINT_MAP = {
      "job_list": "/job.list",
      "job_info": "/job.info",
      "job_search": "/job.search",
      "candidate_list": "/candidate.list",

      "candidate_info": "/candidate.info",
      "candidate_create": "/candidate.create",
      "candidate_create_note": "/candidate.createNote",
      "candidate_list_notes": "/candidate.listNotes",
      "candidate_add_tag": "/candidate.addTag",
      "candidate_tag_list": "/candidateTag.list",
