Best for
  • Developers blocked by OAuth app registration or admin approval
  • Users across Claude Code, Cursor, Copilot, Windsurf, Gemini CLI, and Codex CLI
  • Self-hosters who want tokens and data kept local
  • Users who already rely on Anytype as a personal or collaborative knowledge base
  • Users who want to create and manage Anytype objects quickly with natural language
  • Advanced users running the Anytype desktop app locally who want AI assistant integration
Not for
  • Workspaces whose acceptable-use policy forbids unofficial clients (consider the OAuth hosted tier)
  • Compliance-sensitive environments uncomfortable reusing personal browser session credentials
  • Teams needing official Slack support (not affiliated with Slack Technologies)
  • Users without Anytype installed or running and unable to obtain an API key
  • Scenarios needing a remotely hosted service instead of a local stdio process
  • Users who want zero configuration without setting environment variables
Required permissions
  • Requires Slack browser session token (xoxc-) and cookie (xoxd-); the agent's footprint equals your browser session exactly
  • On macOS, Chrome auto-extraction reads Chrome's local LevelDB and the Chrome Safe Storage key from the Keychain
  • Write tools (send, react, mark read) carry MCP destructive annotations so clients can gate them
  • Requires an Anytype API key passed via an Authorization: Bearer header
  • Needs access to the local Anytype API service (default http://127.0.0.1:31009)
  • Passes authentication headers through the OPENAPI_MCP_HEADERS environment variable, treated as secret
  • Runs an npx command locally as a stdio subprocess
Risks and side effects
  • Automating your own session is a gray area under Slack's terms — this is an unofficial client
  • No app install appears in the admin panel, but traffic is still subject to workspace compliance exports, DLP, and retention
  • Session tokens expire roughly every 1–2 weeks, requiring re-extraction or the hosted OAuth tier
  • Tokens equate to your full Slack session; a leak means a session leak
  • OPENAPI_MCP_HEADERS contains the API key; leaking this configuration can expose Anytype data
  • The server can create and modify spaces, objects and lists on behalf of the key owner
  • Running npx -y downloads and executes package code from npm
  • Pointing ANYTYPE_API_BASE_URL at an untrusted address can send authentication headers there
