The routine a careful trader follows, as one tool call per step:
- Find: tokens by contract address only, never by ticker. Confirm name, decimals and price.
- Check:
token_riskbefore every buy. Honeypots, mint and freeze authorities, taxes, owners, thin liquidity. - Size:
swap_quotewith the minimum out and every fee shown, before anything is built. - Swap:
swap_buildreturns unsigned transactions. Exact-amount approvals only. Your own wallet signs. - Watch:
wallet_holdingsafter the swap, valued at what selling would get now. Airdrops nobody can sell are flagged, not counted.
Instructions only. No scripts, nothing runs on your machine, no keys ever asked for or handled. Read the whole skill in a minute: SKILL.md.
Install
Claude Code: the plugin installs the skill and connects the Fivebar MCP in one go.
/plugin marketplace add fivebar-xyz/skills
/plugin install fivebar@fivebar
Codex, Cursor, GitHub Copilot, Gemini CLI and other agents that read Agent Skills:
npx skills add fivebar-xyz/skills
From a script or another agent (no prompts, every agent on the machine):
npx -y skills add fivebar-xyz/skills -y -g --agent '*'
Then connect the MCP if your agent doesn't have it yet: add https://fivebar.xyz/mcp as a remote (Streamable HTTP) MCP server. Free, no key.
Any agent: the MCP sends a short version of this routine when it connects, and offers three prompts: "Trade a token safely", "Is this token safe?" and "What do I hold?".
Fees
Data tools are free. Swaps built through Fivebar carry a 0.5% fee, paid inside the swap and shown in every quote next to the router's fee and gas.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
