Ashby MCP Server

Instructions

Implementation Reference

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

  The `handle_call_tool` function serves as the central handler for all tools, including "candidate_create_note". It uses the `TOOL_ENDPOINT_MAP` to route requests to the appropriate Ashby API endpoint.

  @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:162-176 (schema)

  Definition and input schema for the "candidate_create_note" tool.

      name="candidate_create_note",
      description="Add a note to a candidate. Supports HTML formatting.",
      inputSchema={
          "type": "object",
          "properties": {
              "candidateId": {"type": "string", "description": "The candidate ID"},
              "note": {"type": "string", "description": "Note content (HTML supported)"},
              "sendNotifications": {
                  "type": "boolean",
                  "description": "Notify subscribed users (default false)",
              },
          },
          "required": ["candidateId", "note"],
      },
  ),

• src/ashby/server.py:382-382 (registration)
