yacy-search MCP server

An MCP server for one YaCy peer: web search without a search API or API key, crawling, ranking settings and search quality evaluation. It runs next to the agent (stdio) and talks to the agent's own peer over HTTP. There is no central service: the peer is yours, and it searches the peer-to-peer network it belongs to. Registry name: io.github.pad01g/yacy-search.

It is written for the improved-search fork (results carry author signature verdicts and tags). Search, crawl, status and settings also work with upstream YaCy.

Run

Start a peer and the MCP server on one Docker network:

docker network create yacy 2>/dev/null || true

docker run -d --name yacy --network yacy -p 127.0.0.1:8090:8090 \ -v yacy_data:/opt/yacy_search_server/DATA ghcr.io/pad01g/yacy-improved-search:latest

Claude Code

claude mcp add yacy -- docker run -i --rm --network yacy \ -e YACY_URL=http://yacy:8090 -e YACY_ADMIN_PASSWORD=' ' ghcr.io/pad01g/yacy-search-mcp:1.0.0

The fork's image starts with the administrator account admin / yacy: change the password at http://127.0.0.1:8090/ConfigAccounts_p.html before connecting the MCP server, and pass the new one.

Other clients (mcp.json style):

"mcpServers": { "yacy": { "command": "docker", "args": ["run", "-i", "--rm", "--network", "yacy", "-e", "YACY_URL=http://yacy:8090", "-e", "YACY_ADMIN_PASSWORD= ", "ghcr.io/pad01g/yacy-search-mcp:1.0.0"] } } }

For a peer outside Docker use -e YACY_URL=http://host.docker.internal:8090 (Linux: add --add-host=host.docker.internal:host-gateway). Without Docker: npm ci && node src/server.ts in this directory (Node 24).

Variable	Default	Meaning
`YACY_URL`	`http://localhost:8090`	base URL of the peer
`YACY_ADMIN_USER`	`admin`	administrator account (crawl, status counts, settings)
`YACY_ADMIN_PASSWORD`	unset	administrator password; without it `crawl_site`, `control_crawl`, `delete_document` and `set_ranking_setting` are refused (even if the peer accepts local requests without a password), and the reading admin tools work only where the peer allows them without one
`YACY_CRAWL_ALLOW_PRIVATE`	unset	`1`: `crawl_site` may reach loopback and private addresses (an intranet). Otherwise only http(s) URLs of public hosts. This checks the start URL only; the links and redirects YaCy follows are limited by YaCy's own `network.unit.domain` (`global` on public peers refuses local addresses)
`YACY_TIMEOUT_MS`	`30000`	timeout of one request to the peer
`YACY_ALLOW_TRUST_SETTINGS`	unset	`1`: `set_ranking_setting` may also change `trust.search.acceptUnverified` and `trust.policy.excludeTags`

On the improved-search fork, the vector search (short questions find pages without the exact words) is used only for searches of the peer's administrator or from its host. When the MCP server runs in another container, set search.vector.public=true on the peer (it then embeds every new query of its search page).

Tools

Tool	What it does
`search_web`	full-text search; `resource: "global"` also asks connected peers and waits `waitMs` before ranking all answers
`crawl_site`	start a crawl (`url`, `depth`, `range`: domain / subpath / wide, `maxPages` per host, default 200)
`get_index_status`	indexed documents, crawl queues, peer type and connections; explains a paused crawler (load average) and a peer without a public address
`list_peers`	connected peers: signed seed, reach (direct / relay), tags
`get_ranking_settings`	the ranking and filtering settings with their meaning
`set_ranking_setting`	change one of them (allow-list only: minimum match, coverage and thin page weights, title phrase boost, wait time; unverified results and excluded tags only with `YACY_ALLOW_TRUST_SETTINGS=1`)
`evaluate_ranking`	queries with known relevant URLs: precision@k, recall@k, R-precision, the rank of each relevant URL; finishes within about 50 s (queries that do not fit are reported as `skipped`)
`get_trust_status`	the signed delegations and peer lists the peer holds
`list_crawls`	the crawls started on the peer, with the handle `control_crawl` needs
`control_crawl`	pause or resume the local crawler, or stop one crawl (indexed pages stay)
`delete_document`	remove one page from the peer's own index (stop a running crawl of that site first)

1.0.0 renamed the tools to a consistent verb_noun form (no aliases): search → search_web, crawl → crawl_site, crawls → list_crawls, crawl_control → control_crawl, index_status → get_index_status, peers → list_peers, trust_status → get_trust_status. Clients that call tools by name need the new names.

A typical loop for improving results: evaluate_ranking → set_ranking_setting → evaluate_ranking.

Titles and snippets come from page authors and other peers: the tool descriptions tell the model to treat them as data, not instructions. crawl_site, control_crawl, delete_document and set_ranking_setting are marked destructive so that clients ask before calling them. Values of settings are checked per key, and a value YaCy stores differently is rolled back.

Test

npm ci && npm run typecheck && npm test                      # unit tests

YACY_URL=http://localhost:8090 YACY_ADMIN_PASSWORD=yacy npm test # also calls every tool on a live peer
