Skills, MCP Servers & Env Vars

Bankr is extensible. Install skills, connect MCP servers, and store secrets — all per-wallet and synced across every surface.

Skills

Skills are pre-packaged workflows the agent can load on demand. Install from GitHub:


"install the ens skill from https://github.com/austintgriffith/ethskills/tree/master/skills/ens"
"install all skills from https://github.com/BankrBot/skills"

Or paste a skill directly in chat:


create a skill with this content:
---
name: my_workflow
description: Runs my custom portfolio report
---
# My Workflow
...

Once installed, the agent picks the right skill automatically. Force it with: use the ens skill to register deployer.eth

Limits: up to 50 skills per wallet, 100KB per file.

MCP Servers

Connect external tools so Bankr can call them — Linear tickets, GitHub PRs, Notion pages, anything.

Web: Settings gear → MCP Servers → + Add

Chat:


"add an MCP server named Linear at https://mcp.linear.app/mcp
with Authorization header Bearer {{LINEAR_API_KEY}}"

Then just ask naturally: show my open Linear issues assigned to me

Limits: up to 20 MCP servers per wallet.

Secure Environment Variables

Store secrets (API keys, tokens) that are never echoed in chat. Set them in Settings → Env Vars, or via the API.

Reference them with {{VAR_NAME}} placeholders in MCP server headers or skill configs.
