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 | $0.00152 | $0.01714 |
| Opus 5 | $0.00076 | $0.00857 |
| Sonnet 5 | $0.00030 | $0.00343 |
| Haiku 4.5 | $0.00015 | $0.00171 |
Grade A, and why
searxng-settings-editor 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 12d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SearXNG Embedded Settings Editor
Reads and edits the embedded SearXNG instance's configuration
(searxng_mcp.embedded, CONCEPT:SR-KG.compute.embedded-instance) — the private,
loopback-only (127.0.0.1) SearXNG process the searxng-mcp server can spawn
and own end to end when no SEARXNG_URL/SEARXNG_INSTANCE_URL is configured,
instead of falling back to a public instance.
When to use
- Turn on/off a response format (e.g. add
csv/rssalongside the defaulthtml+json). - Toggle privacy knobs:
general.enable_metrics,server.image_proxy,search.autocomplete,search.favicon_resolver. - Route the embedded instance's outbound engine requests through a proxy (Tor/VPN/SOCKS) for engine-level anonymity, not just "nothing shared between SearXNG instances".
- Diagnose why the server is using the public
https://searx.befallback instead of a private embedded instance.
When NOT to use
- An external instance is configured (
SEARXNG_URLset) — its settings.yml lives on that host, not here; this skill only ever touches the EMBEDDED instance's config. - You just want to run a search →
searxng-web-search. - You want results persisted to the KG →
searxng-kg-ingestion.
Prerequisites & environment
Connect via the mcp-client skill against the searxng-mcp MCP server.
Embedded mode requires the searxng-mcp[embedded] extra
(pip install 'searxng-mcp[embedded]' — installs SearXNG itself from its git
source, since it ships no PyPI release) on the HOST running the MCP server.
| Variable | Required | Notes |
|---|---|---|
SEARXNG_EMBEDDED |
optional | Default true. Set false to force the public/random fallback even with the extra installed. |
XDG_CONFIG_HOME |
optional | Where the user settings override lives ($XDG_CONFIG_HOME/searxng-mcp/settings.yml); defaults to ~/.config. |
Tools & actions
| Tool | Purpose |
|---|---|
searxng_settings |
get / set / reset the embedded instance's settings.yml. |
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-settings-editor is a skill published in the GitHub repository Knuckles-Team/searxng-mcp (2 stars, last pushed 15d ago), licensed MIT. It adds 152 tokens to every session and 1,714 once invoked, about $0.0008 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.
