Compatible with every major AI agent and IDE
What is the Treblle MCP Server?
Connect your Treblle account to your AI agent to streamline API monitoring and observability. This server allows you to send API traffic data directly to Treblle, helping you maintain high-quality documentation and security standards.
What you can do
- API Ingestion — Send full request and response payloads to your Treblle dashboard using the
ingest_api_datatool. - Observability — Monitor API performance and errors in real-time as your agent processes or simulates traffic.
- Automatic Masking — Ensure security with Treblle's built-in masking for sensitive fields like passwords and credit card numbers.
- Custom Metadata — Attach trace IDs, user IDs, or environment identifiers to your ingested data for better filtering.
How it works
- Subscribe to this server
- Enter your Treblle API Key and SDK Token
- Start ingesting API data directly from your conversation or automated workflows
Who is this for?
- Backend Developers — quickly log and debug API interactions without manual instrumentation
- DevOps Engineers — monitor API health and traffic patterns directly from the terminal or AI assistant
- QA Engineers — capture and report API errors with full context during testing phases
Built-in capabilities (1)
Sensitive fields (passwords, CCs, SSNs) are automatically masked before transmission. Send API request/response data to Treblle
Why Cursor?
Cursor's Agent mode turns Treblle into an in-editor superpower. Ask Cursor to generate code using live data from Treblle and it fetches, processes, and writes. all in a single agentic loop. 1 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
How do I send API traffic data to my Treblle dashboard?
Use the ingest_api_data tool. You need to provide the JSON payload containing the server, request, and response information as defined in the Treblle schema.
Is my sensitive data like passwords or credit cards safe when ingesting?
Yes. Treblle automatically masks sensitive fields (passwords, CCs, SSNs) before the data is transmitted and stored, ensuring compliance and security.
Can I add custom identifiers like a trace-id to the ingested data?
Absolutely. You can use the optional metadata parameter in the ingest_api_data tool to include flat key-value pairs like trace-id, user-id, or env-id.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
