Hours lost to connection debugging
Copying stale MCP examples, guessing auth headers and discovering timeouts only after the agent starts work.
The missing starting point for agent builders
Free MCP tools for a working agent setup.
Start with tested MCP configs, safe CLI tools and repeatable workflows instead of spending day one hunting docs, debugging JSON and wiring the same utilities again.
No account for downloadsNo npm install for CLI toolsWorks with Cursor and MCP hosts
Live cheaperllm MCP, 14 downloadable CLI tools in /tools/bin/, and ready-to-ship packs.
The setup tax
A blank agent is not a working system.
The model is only one piece. Reliable agents also need tool discovery, bounded fetches, schema checks, cost visibility, environment gates and replayable logs.
Attach, probe, then build
Use a ready-made config and verify the endpoint before trusting it with a production workflow.
Repeat the same safe workflow
Use prompt linting, token metering, bounded fetches and session tapes instead of inventing guardrails per project.
Free kit: configs, tools and workflows. Optional paid layer: one CheaperLLM key for live multi-model routing.
Get a free API keyQuick start
Start in 60 seconds
Key → MCP JSON → probe. Three steps to a live cheaperllm bridge in Cursor or any MCP host.
Get your API key
Sign up at cheaperllm and copy your key. Export as CHEAPERLLM_API_KEY — never commit it into JSON.
Paste MCP JSON
Set url to https://mcp.cheaperllm.com/mcp and Authorization: Bearer your key. Ready-made JSON is in the attach pack.
Verify
Run mcp-probe from /tools/bin/ — expect tools listed, not a timeout.

MCP endpoints — copy & attach
HTTP MCP bridges you can wire today. Catalog discovery is a JSON fetch — not an MCP server.

MCP tools FAQ
Start with a tested connection, then build
The shortest path from a blank agent to a repeatable tool workflow.
What are MCP tools?
Capabilities exposed through the Model Context Protocol, such as fetching data, reading files or calling an API. Browse the 14 free MCP and agent tools.
Do downloads require an account?
No. Tools, configs, prompt packs and workflow files are directly downloadable from the download catalog.
Can I use them with Cursor?
Yes. Start with the Cursor MCP configuration pack, then probe the endpoint before building.
What should I install first?
Follow the getting-started guide: attach one MCP, run mcp-probe, then add workflows and prompts.
