X (Twitter) MCP Server

Score Breakdown
⚙ Agent Friendliness
🔒 Security
OAuth2. Bearer token stored as env var. Public platform but user data is PII. ToS compliance required — no automation that violates X policies.
⚡ Reliability
Best When
An agent needs to read or post to X as part of a content or social media workflow — with appropriate rate limit management and ToS compliance.
Avoid When
You need high-volume data access (X API costs have increased significantly) or automation that would violate X's terms of service.
Use Cases
- • Publishing tweets and threads from content marketing agents
- • Searching and analyzing tweet sentiment from social listening agents
- • Monitoring brand mentions and hashtags from PR agents
- • Engaging with replies and DMs from community management agents
- • Tracking trending topics and influencer activity from market research agents
- • Automating social media posting schedules from content calendar agents
Not For
- • Mass automated posting (violates X terms of service for spam)
- • Data scraping at scale without X Enterprise API access
- • Personal data harvesting or user tracking without consent
Interface
Authentication
X API OAuth2 with Bearer token for read-only or user OAuth2 for write access. X API tiers: Free (very limited), Basic ($100/mo), Pro ($5000/mo). Configure X_BEARER_TOKEN or OAuth credentials as env vars.
Pricing
X API pricing has increased dramatically since Elon Musk acquisition. Free tier is very restrictive. Basic ($100/mo) needed for meaningful usage. Costs are significant for production use.

Known Gotchas
- ⚠ X API pricing has dramatically increased — verify current costs before building on X API
- ⚠ Free tier is extremely limited (500 tweets/month) — meaningless for agent use
- ⚠ X API has changed significantly since 2023 — check current API documentation carefully
- ⚠ Rate limits are strict and can block agents for 15+ minute windows — implement backoff
- ⚠ X Terms of Service: automated posting must be disclosed; no spam; no coordinated inauthentic behavior
- ⚠ API instability: X has made frequent breaking changes to API endpoints since 2022
