Harny Context MCP

Harny Context provides a private memory system for AI agents, allowing each user to have a dedicated memory space that tracks facts, history, and preferences. It enables agents to act on behalf of users within set permissions, maintaining a record of actions and ensuring data privacy across multiple users.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Passed Official MCP Registry namespace is tied to harny.ai ·
  • Passed Endpoint is on the registry namespace domain ·

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Harny MCP server — bootstrap, OAuth, diagnose, and context assembly tools for the first-wedge agent integration (describe, get_snippet, diagnose, provision_app, provision_user, configure_oauth, assemble_context). Connected with a runtime token for one end user, the tools are assemble_context, action_history, calendar_create_event, email_send, ticket_create, slack_post_message, notion_create_page and undo_action, as the token's scopes allow.

provision_app — Provision App
Advertised by the server during the last successful anonymous check.

Set up long-term memory for an app with no account: makes a new app and its key, as `POST /v1/auth/provision` does. The answer carries the app key once, and the assistant is told to put it in the owner's secret store and nowhere else. Needs no key.

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (1 of 1 answered).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http harny-context-mcp https://api.harny.ai/v1/mcp/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add harny-context-mcp --url https://api.harny.ai/v1/mcp/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable harny-context-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "harny-context-mcp": {
      "url": "https://api.harny.ai/v1/mcp/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "harny-context-mcp": {
      "type": "streamableHttp",
      "url": "https://api.harny.ai/v1/mcp/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start harny-context-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "harny-context-mcp": {
      "type": "http",
      "url": "https://api.harny.ai/v1/mcp/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http harny-context-mcp https://api.harny.ai/v1/mcp/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://api.harny.ai/v1/mcp/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "harny-context-mcp": {
      "serverUrl": "https://api.harny.ai/v1/mcp/mcp"
    }
