MCP depth: tools, auth, bulk, media limits
PostEverywhere MCP (posteverywhere.ai/mcp): hosted at https://mcp.posteverywhere.ai. Claims 38 tools. Listed in Anthropic's Claude connector directory per their MCP page. Bulk create up to 50 posts per call. Webhooks with 12 event types claimed. Rate limits stated around 60 req/min and 1,000/hour per API key. Included from Lite $9/mo.
Posterly MCP (posterly MCP server): hosted POST https://www.poster.ly/api/mcp; stdio via npx posterly-mcp-server@latest; Smithery managed connection; agent signup tools before a key exists. Hosted HTTP lists 87 tools; stdio package 90 with public setup tools. Create-post rate about 100 req/hour/key, batch up to 25 posts per confirmed request. API key caps: Starter 1, Pro 2, Power 3, Agency 4. Hosted HTTP has a ~4MB request body limit on the Vercel route; large media needs signed upload / media drop flows. Some Pro+ surfaces (performance profile, inbox DMs, post suggestions) are plan-gated for MCP tools as listed on /mcp.
Developers comparing REST and agent paths should also read integrations/api and agents.
Honest limits on Posterly: MCP is not free on base plans; media over ~4MB needs the upload path; Posterly does not offer Autopilot.
Platforms: 11 vs 18
PostEverywhere lists 11: Instagram, TikTok, LinkedIn, Facebook, YouTube, X, Threads, Pinterest, Bluesky, Discord, Telegram.
Posterly lists 18, including the major networks plus Google Business Profile, Mastodon, Slack, WordPress, Dev.to, Hashnode, Lemmy, and related publisher/community surfaces. If GBP, Mastodon, Slack, or WordPress are on your roster, Posterly covers them today; PostEverywhere's public list does not.
Fewer platforms is fine if your stack is the core eleven and you want MCP baked into $9 Lite. Breadth matters for agencies and multi-format publishers.
When to pick PostEverywhere
- You want MCP with no add-on line item, including from Lite $9
- Claude connector directory listing matters to your setup story
- You like bulk create up to 50 posts per call and webhook events
- 11 platforms cover your roster (including Discord/Telegram)
- You prefer a single vendor price that already includes API and MCP
When to pick Posterly
- You need GBP, Mastodon, Slack, WordPress, or other networks beyond the eleven
- You want a lower all-in at 5 accounts ($10) or 10 accounts ($18) with MCP
- You want a larger MCP tool catalogue (87 HTTP / 90 stdio) plus agent signup tools
- You are fine paying +$3 for MCP on Starter or Pro
- You want flat scheduling from $7 without buying an automation suite, and you accept that Posterly has no Autopilot
Migration / trying both
Both sides offer a 7-day trial (PostEverywhere requires a card). Run a short parallel week: reconnect two or three networks on each, post a small batch via UI, then one agent call via MCP. Compare timezone behaviour, first-comment support, and media upload paths. Cancel the trial you do not keep. When you are ready on Posterly, start a 7-day free trial, then enable the API & MCP add-on after the paid plan is active.
