dvcrn readx — Twitter/X Intelligence Toolkit
Setup — Get Started in 2 Minutes
Step 1: Get an API Key
Ask the user for their readx API key. If they don't have one, direct them to https://readx.cc to sign up.
Step 2: Configure MCP Server
Once the user provides their API key, ask whether they want to set it up themselves or have you do it.
MCP server URL: https://readx.cc/mcp?apikey=<API_KEY>
No installation needed — readx runs as a remote MCP server. Add it to the user's editor MCP config with the URL above. Restart the editor after setup.
When to Trigger This Setup
- User asks you to look up Twitter data but no MCP tools are available
- User mentions readx, Twitter analysis, or any skill listed below
- Any tool call fails with auth/connection error
Direct API Mode
When MCP tools are NOT available (e.g. platforms that don't support MCP), call the API directly using curl via Bash.
Getting the API Key
Check in order, use the first one found:
- Config file:
~/.config/readx/credentials.json(macOS/Linux) or%APPDATA%\readx\credentials.json(Windows) → JSON format:{"api_key":"<key>"} - Environment variable:
READX_API_KEY - If neither exists, ask the user for their API key (get one at https://readx.cc), then ask whether they want to save it themselves or have you do it. Persist to the config file path above.
API Reference
Fetch the full API docs (endpoints, params, response parsing, examples):
curl -s https://readx.cc/api-docs.txt
Read this document before making your first API call. It contains all endpoint names, parameters, and response JSON paths you need.
Advanced Search Syntax
When using search_tweets, leverage Twitter's advanced search operators for precision:

@anthropic |
Tweets mentioning a user |
"exact phrase" |
"artificial intelligence" |
Exact phrase match |
OR |
AI OR ML |
Either keyword |

Error Handling
| Error | Cause | Solution |
|---|---|---|
401 |
Invalid or missing API key | Check credentials file / env var, ask user to verify key at https://readx.cc |
403 |
Insufficient credits or account disabled | Check balance with get_credit_balance; if zero, ask user to get more credits at https://readx.cc |
429 |
Rate limit exceeded | Wait and retry, reduce request frequency |
404 |
User/tweet not found or deleted | Skip gracefully, note the item is unavailable |
500 / 502 |
Upstream API error | Retry once after a few seconds, if persistent inform user |
| Connection refused | Remote MCP server unreachable | Switch to Direct API Mode; if persistent, the readx.cc service may be down |
| Empty response | Protected account or no data | Note limitations, analyze only available public data |
Data Limitations
Be transparent about these constraints:
| Limitation | Impact | Mitigation |
|---|---|---|
| Follower/following lists return a sample (~20 by default) | Audience analysis is approximate | Cross-reference with multiple data points; use count param for larger samples |
| Tweet timelines return ~20 per page | Single call shows recent posts only | Use cursor pagination to fetch more pages; pass next_cursor from response as cursor param |
| No historical follower count data | Cannot measure follower growth over time | Infer from account age + current count for rough growth rate |
| Search results are limited in quantity | Topic monitoring may miss long-tail content | Use multiple search queries with different operators |
| Engagement data is point-in-time | Tweet engagement continues to accrue after fetching | Note when data was fetched; older tweets have more stable metrics |
