What is the PostFast MCP server?

The PostFast MCP server lets Claude, Cursor, Codex, and other MCP-compatible clients query posts, schedules, engagement metrics, and mentions without leaving the editor. The server is official, hosted by PostFast themselves, so it should track product changes without lag.

Three things you actually do with it: ask Claude which post types drive the most clicks this month, have Cursor draft a follow-up to your top-performing thread, and let Codex schedule a post across LinkedIn and X with one prompt.

PostFast also has a public REST API at postfa.st. Use the API for scheduled jobs and custom dashboards. Use the MCP server when an LLM is in the loop.

For the rest of the picture see the PostFast review.

Does PostFast MCP cost extra?

Included with subscription

PostFast ships an official MCP server that uses your existing subscription credentials.

  • No separate MCP licence to buy. You pay for your PostFast 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.

PostFast also publishes a REST API

PostFast publishes an API, but per-tier gating wasn't extracted automatically.

What you can do with PostFast from an AI agent

Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.

INDIE / SOLO

Skip the dashboard, ask Claude

  • "What changed this week?" answered in seconds
  • Quick one-off questions without leaving the editor
  • Pipe PostFast data into your personal notes / docs without writing a script
Effort: 30 seconds — paste the config, restart Claude
AGENCY

Run client analysis at agent speed

  • Hand the MCP server to your team — every consultant can ask Claude about any client's PostFast account
  • Multi-account workflows without context-switching the PostFast UI
  • Reports you'd normally spend hours on, done before standup
Effort: An afternoon — set up auth per client
IN-HOUSE TEAM

Production agent workflows

  • Embed in your internal Codex / Cursor agents that triage PostFast data daily
  • Combine with other MCP servers in a multi-step agent chain
  • Constrain agents to read-only roles to keep production PostFast safe
Effort: Days — security review + role config

Limits and gotchas

  • Official MCP server — published by PostFast themselves, so it should track product changes.
  • Fallback: the REST API works for any flow the MCP server doesn't cover.
  • Rate limits: MCP calls count against your underlying PostFast API quota. Burst usage from a curious agent can drain a daily allowance fast.
