Install

How do I install the Cofferline MCP server?

Cofferline is a hosted endpoint at https://mcp.cofferline.com/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the Cofferline MCP server?

Cofferline is an MCP server listed in the public MCP registry as com.cofferline/treasury. Treasury and risk controls for agent wallets: policies, quotes, prediction-market orders. This page covers its hosted endpoint (https://mcp.cofferline.com).

Is the Cofferline MCP server safe to use?

Cofferline scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Cofferline MCP server expose?

Cofferline exposes 47 tools: get_quotes, get_benchmarks, screen_address, list_tokens, list_feedback, and 42 more. Their descriptions and schemas cost roughly 3,517 tokens of context every time the server is loaded.

Does the Cofferline MCP server require authentication?

No. We connected to Cofferline without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Cofferline MCP server still maintained?

Cofferline is still listed as active in the MCP registry. We last reached this channel on 27 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
