Grammarly integration for AI agents.
Grammarly integration for AI agents with secure authentication and server-side credential injection. Open Connector runs the OAuth, seals the token in an encrypted vault, and serves Grammarly tools to your agent over MCP or a typed API — credentials injected server-side, every call audited, nothing leaving your infrastructure. Open source (AGPL-3.0) and self-hostable.
Real Grammarly actions, managed and audited.
Your user connects Grammarly once; your agent can then secure AI-agent actions — scoped to the OAuth permissions you grant and the tool allowlist you configure. Every action is least-privilege and written to a tamper-evident audit trail.
- 1
Your user grants Grammarly access once (OAuth) — the token lands in the vault.
- 2
Your agent calls a tool over MCP or the typed API; Open Connector injects the credential server-side.
- 3
Every routed call appends a hash-chained audit record — nothing leaves your infra.
Grammarly tool surface.
The following managed tool groups are exposed by this integration. Each item is surfaced as tool metadata so agents can discover safe actions and build reliable workflows.
- Grammarly tools
- Secure AI-agent actions.
Grammarly integration, answered
- How do AI agents use Grammarly through Open Connector?
- Your user connects Grammarly once with one of its cataloged authentication methods. Open Connector stores the credential in an encrypted vault and exposes Grammarly tools to your agent over MCP or a typed API, with credentials injected server-side on each call.
- Is this a Grammarly MCP server?
- Yes. Open Connector can serve Grammarly as a named MCP server with a scoped allowlist and a per-user connection URL, so any MCP client can call Grammarly actions with credentials injected server-side.
- Where do Grammarly credentials live?
- In your own infrastructure. Open Connector keeps credentials in its own vault and injects them at call time, so they never leave your environment.
