Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00821 |
| Opus 5 | $0.00018 | $0.00411 |
| Sonnet 5 | $0.00007 | $0.00164 |
| Haiku 4.5 | $0.00004 | $0.00082 |
Grade A, and why
x-social scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Bypassing MCP with curl/fetch/scripts How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
X Social
Use xeng-mcp tools only. The host already supplies credentials and upstream routing — do not invent REST clients, env exports, or endpoint URLs.
When to use
- Topic clustering (themes, narratives, communities)
- Trend comparison across time windows
- Campaign / hashtag monitoring
- Market and sales signal reading (intent, complaints, competitors)
Rules
- Call
xeng_healthonce if connectivity is uncertain; otherwise start withxeng_search. - Prefer several focused
xeng_searchcalls over one vague query. - Cite evidence with
tweet_idandscreen_namefrom returned rows only. - Treat pagination as a sample, not a full corpus or market share.
- Never fabricate tweets, authors, or engagement. Never print secrets.
- Do not shell out to HTTP, invent paths, or ask the user for a base URL — MCP tools are the API.
xeng_search
Required: q.
Optional: page, limit (max 100), offset, lang, screen_name, hashtag (no #), mention (no @), from_created_at, to_created_at, include_raw_json.
xeng_search:
q: "<topic or keyword>"
limit: 50
hashtag: "<tag without #>"
from_created_at: "<ISO lower bound>"
to_created_at: "<ISO upper bound>"
Use response metadata.pagination when present for sample size; do not invent totals.
Procedures
Clustering
- Seed search on the topic (
limit50–100); add synonym / slang / competitor queries as needed. - Group hits by theme (praise, complaint, meme, policy, spam, product, other).
- Per cluster: label, sample size, representative quotes, recurring hashtags/mentions.
- State that clusters are sample-based.
Trends
- Fix
q(and optionalhashtag/mention). - Repeat
xeng_searchacross sequentialfrom_created_at/to_created_atwindows. - Compare sample counts and engagement fields present on rows; note rising/falling themes and amplifiers only from data.
- Empty window → report empty; do not extrapolate.
Campaign monitoring
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

x-social is a skill published in the GitHub repository hinha/xeng-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 821 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
