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 | $0.00138 | $0.01221 |
| Opus 5 | $0.00069 | $0.00611 |
| Sonnet 5 | $0.00028 | $0.00244 |
| Haiku 4.5 | $0.00014 | $0.00122 |
Grade A, and why
searxng-web-search scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SearXNG Web Search
Privacy-respecting metasearch over the searxng-mcp server. One web_search
call fans a query across many upstream engines and returns a merged, ranked JSON
result set — without exposing the query to any single tracker.
When to use
- Answer "what's out there about X" with fresh open-web results.
- Gather candidate source URLs to hand to
web-fetch/web-crawlerfor full reads. - Category-scoped search: general,
news,science,it,files,images,videos,music,social_media.
When NOT to use
- Academic / preprint literature →
scholarx. - Fetch or scrape the full content of a specific known URL →
web-fetch/web-crawler. - Keyless social-platform research (X, Reddit, YouTube, HN) →
pulselink-mcp. - You want results persisted into the knowledge graph →
searxng-kg-ingestion.
Prerequisites & environment
Connect via the mcp-client skill against the searxng-mcp MCP server.
| Variable | Required | Notes |
|---|---|---|
SEARXNG_INSTANCE_URL |
optional | Instance base URL (alias SEARXNG_URL). Falls back to https://searx.be. |
SEARXNG_EMBEDDED |
optional | Default true. With no URL configured + the searxng-mcp[embedded] extra installed, spawns+uses a private loopback-only instance BEFORE falling to a random/public one — see searxng-settings-editor. |
USE_RANDOM_INSTANCE |
optional | If truthy and no URL/embedded instance available, pick a random public instance from the SearXNG instances list. |
SEARXNG_USERNAME / SEARXNG_PASSWORD |
optional | HTTP basic auth for a protected instance. |
SEARXNG_KG_INGEST |
optional | Default-on; set falsy to disable the background KG ingest on web_search. |
MCP_TOOL_MODE |
optional | condensed | verbose | both. |
Tools & actions
| Tool | Purpose |
|---|---|
web_search |
Run a metasearch query and return the raw SearXNG JSON. |
Key parameters
query— the search string (required).categories— list, e.g.["news"]or["science"].engines— restrict to specific engines, e.g.["duckduckgo","wikipedia"].language— BCP-47ish code, defaulten-US.pageno— 1-based result page for paging deeper.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

searxng-web-search is a skill published in the GitHub repository Knuckles-Team/searxng-mcp (2 stars, last pushed 14d ago), licensed MIT. It adds 138 tokens to every session and 1,221 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
