Access, auth, and limits
Auth is a personal Frase API key supplied to the local process, and Frase makes a point of the boundary: the key reaches only your account data, the connection is encrypted, and the key stays in your local config rather than being handed to whoever runs your assistant. That is the right trade for a tool that can publish to your CMS.
Pricing is refreshingly simple. The MCP server is included with Frase from $39/mo billed yearly, with no separate add-on, and activity through the server counts against the same plan limits as the app, so the briefs, audits and content you already pay for are the same pool. Seats and audit credits are the things you add as a team grows.
One thing worth knowing if you go looking: Frase publishes a /.well-known/mcp.json that also declares a hosted server at next.frase.io/api/mcp using OAuth 2.0, and that endpoint does answer. It is not mentioned anywhere on Frase's MCP page, which documents the npm route only, so treat the hosted endpoint as undocumented rather than as a supported alternative until Frase says otherwise.
Where it works and what to build
The natural workflow: tell your agent "research 'best CRM for small business,' build a content brief from the top-ranking pages, draft a 1,500-word article against it, then audit the draft for optimization gaps." Frase's tools cover every step of that chain, so the agent doesn't hand you a half-finished job.
Claude Code gets native support, which is the sweet spot for anyone running content ops from a terminal or a repo. Cursor and Claude Desktop can run the same npx server, though it's a bridge rather than a named integration, so expect to do a little config work rather than picking Frase from a dropdown.
Which AI clients can use Frase MCP?
Not every AI assistant supports MCP natively. Per-client picture for Frase:
| Client | Support | Notes |
|---|---|---|
| Claude Code | Native MCP | Install via `claude mcp add frase -- npx -y @frase/mcp-server`; authenticate with FRASE_API_KEY. |
| Claude (Desktop/Web) | Third-party bridge | npm-based local MCP server (@frase/mcp-server) run via npx; documented for AI coding assistants and custom workflows. |
| Cursor | Third-party bridge | Local MCP server runnable via npx; not explicitly named but MCP is aimed at AI coding assistants. |
Does Frase MCP cost extra?
Frase ships an official MCP server that uses your existing subscription credentials.
- No separate MCP licence to buy. You pay for your Frase plan, the MCP server queries that account.
- Whether it's gated to a specific tier wasn't extracted automatically — verify the access requirements on the MCP page or pricing docs.
Frase also publishes a REST API
Frase publishes an API, but per-tier gating wasn't extracted automatically.
What you can do with Frase from an AI agent
Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.
Skip the dashboard, ask Claude
- "What keywords moved this week?" answered in seconds
- Quick one-off questions without leaving the editor
- Pipe Frase data into your personal notes / docs without writing a script
Run client analysis at agent speed
- Hand the MCP server to your team — every consultant can ask Claude about any client's Frase account
- Multi-account workflows without context-switching the Frase UI
- Reports you'd normally spend hours on, done before standup
Production agent workflows
- Embed in your internal Codex / Cursor agents that triage Frase data daily
- Combine with other MCP servers in a multi-step agent chain
- Constrain agents to read-only roles to keep production Frase safe
Limits and gotchas
- Official MCP server — published by Frase themselves, so it should track product changes.
- Fallback: the REST API works for any flow the MCP server doesn't cover.
- Auth flow: MCP servers usually inherit the underlying API auth method (api_key). Expect to configure that on first install.
- OpenAPI spec is published — easy to validate which endpoints the MCP server actually exposes vs the full API surface.
- Rate limits: MCP calls count against your underlying Frase API quota. Burst usage from a curious agent can drain a daily allowance fast.
Agent-readiness verdict
A 63-tool surface covering research through publishing, included in the plan you already pay for rather than sold as an add-on, with an approval gate before anything reaches your CMS. The cost is a one-time local install rather than a click-to-connect URL.
Moderate agent-fit with community MCP support. Frase offers a documented public API and native Claude integration, but lacks official MCP hosting, OpenAPI specs, and structured outputs that would unlock fuller agentic capabilities. The community MCP server bridges some gaps, though relying on third-party maintenance introduces continuity risk.
