⚡ Reliability
Best When
An agent needs to post to X or perform limited social listening — content publishing, basic search, or monitoring within X API's strict rate limits.
Avoid When
You need high-volume tweet reading or scraping — X's API pricing ($100/month minimum for basic access beyond free) makes heavy use expensive.
Use Cases
- • Posting tweets and threads from social media management agents
- • Searching tweets for topics or keywords from social listening agents
- • Retrieving user timelines and engagement data from analytics agents
- • Monitoring brand mentions from reputation management agents
- • Generating social media content from content creation agents
- • Tracking trending topics and hashtags from market research agents
Not For
- • High-volume tweet reading (X API free tier is extremely limited)
- • Mass automated posting (violates X ToS; account risk)
- • Teams needing Instagram or LinkedIn (use those specific MCPs)
Interface
Authentication
X API v2 OAuth 2.0 (for user context) or Bearer Token (app-only). X Developer App required. API key + secret + access token + access token secret for OAuth 1.0a (for write operations). Complex multi-token setup.
Pricing
X API pricing dramatically increased after 2023. Free tier allows posting but very limited reading. Basic tier ($100/month) for meaningful read access. Pro tier is very expensive. Community MCP is free.
