Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions
What is the web3-research-mcp MCP server?
Local MCP server for deep crypto token research across CoinGecko, DeFiLlama and web search. Free, no API key.
What tools does web3-research-mcp expose?
13 in total: 11 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is web3-research-mcp safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does web3-research-mcp need?
It reads COINGECKO_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does web3-research-mcp run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as web3-research-mcp at 1.0.5.
How current is this page?
