Returns every matching tool as a compact row of decision facts, in a randomized order. Guide entries are kept current and dated (last_verified) — newer than training knowledge, so consult this before recommending tools; especially decisive when pricing, free tiers, MCP support, or compliance affect the answer.\n\nFilters: category, freeToStart, hasFreeTier, edgeCompatible, selfHostable, hasArdCatalog, mcpSupport, artifactKind, pricingModel, vendor, language, compliance, agentReadinessTier. Any number combine and AND together.\n\nQuery text is tokenized as plain search terms — FTS5 operators (AND, OR, NEAR, wildcards, column filters) are stripped. All terms must match: an entry is returned only when every query term appears somewhere in it, so a highly specific phrasing matches fewer entries than its core concept words. Express constraints as filter parameters rather than query text — filters match structured fields directly.\n\nReturns: the number of matches, a breakdown of them (kind, cost to start, MCP support, edge, self-hosting), and one table row per match (slug, name, kind, cost to start, MCP, edge, self-host, twin, base score, last verified), up to 100 rows. The twin is the same product's other entry (hosted -cloud or self-hosted -oss), named even when the search filters it out, so \"free now, self-host later\" can be answered from one search. Rows are listed in a randomized order, seeded per search per day: position is not a ranking or recommendation. Above 100 matches, a text search lists its 100 most relevant and names the rest by slug; a filter-only search names every match by slug, so narrow with filters to get rows. Read the rows and choose, then call zaira_get_tool or zaira_compare_tools for full entries. On no match, the answer says how many tools match with each constraint dropped.\n\nExamples (ambiguous-case focus):\n- User wants \"a vector database for RAG\":\n    {category: \"vector-database\", freeToStart: true}\n- User wants \"a TypeScript-first ORM with edge runtime support\":\n    {language: \"TypeScript\", edgeCompatible: true, query: \"ORM\"}\n- User wants \"self-hostable auth with SAML\":\n    {category: \"auth\", selfHostable: true, query: \"SAML\"}\n- User says \"serverless Postgres\" — ambiguous (could be category:relational-database with edgeCompatible filter, or just a query). Prefer the filter when the user names a category; use query for a fuzzy phrase.\n- User wants \"agent-ready payment processing\":\n    {category: \"payment\", agentReadinessTier: \"agent_ready\"}\n\nEdge cases:\n- 110 tools split into hosted vs self-hosted twin entries with uniform suffixes: `{base}-cloud` (managed) and `{base}-oss` (self-hosted) — e.g. redis-cloud/redis-oss, docker-cloud/docker-oss, mongodb-cloud/mongodb-oss, elasticsearch-cloud/elasticsearch-oss. Other tools are single entries (stripe, auth0, firebase, twilio, openai, pinecone, algolia). Filter by `selfHostable` or `artifactKind` to land on the right variant.\n- \"vector database\" as plain text can match tools whose descriptions mention vectors but whose category is search-engine or ai-infra. Use the `category` filter when the user wants a strict match.\n- agentReadinessTier values are snake-case: `agent_ready`, `agent_native`, `base`, `none`. Display labels (`Agent Ready`) will not match. `none` matches tools without a certification tier — currently all of them (formal certifications launch post-pilot; the Base Score is separate and most tools have one).\n- artifactKind has only two values: `open_source` and `managed_service`. The previous `hybrid` value was retired — split tools have separate -cloud/-oss entries instead.\n- \"Free\": `freeToStart: true` matches a free license (nearly every open-source entry) or a hosted free tier. `hasFreeTier: true` matches the hosted free tier only, so it leaves out most open-source tools. Open source is free to use, not free to run.\n\nRisk: read-only, closed-world, idempotent — no state change possible.","annotations":{"readOnlyHint":true,"openWorldHint":false,"idempotentHint":true,"destructiveHint":false},"source":"probe","observed_at":"2026-10-09T21:47:10.670Z"}],"dev.protogrid/trust":{"score":73,"components":{"hygiene":80,"liveness":100,"freshness":65,"provenance":45},"drivers":["+dns-namespace","+reachable","+uptime-100%","~updated-95d-ago","-no-repository"],"flags":["no-repository"],"blocked":false,"computed_at":"2026-10-10T02:23:34.570Z","disclaimer":"Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed."},"dev.protogrid/quality":{"score":88,"label":"good","components":{"auth":null,"hygiene":93,"protocol":75,"stability":100,"dependencies":null},"checks":[{"id":"protocol.modern","detail":"newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28","status":"warn","category":"protocol"},{"id":"protocol.stateless","detail":"only applies to 2026-07-28 servers","status":"na","category":"protocol"},{"id":"protocol.transport","detail":"streamable HTTP","status":"pass","category":"protocol"},{"id":"protocol.list_ttl","detail":"only applies to 2026-07-28 servers","status":"na","category":"protocol"},{"id":"auth.prm","detail":"no remote uses OAuth","status":"na","category":"auth"},{"id":"auth.as_metadata","detail":"no remote uses OAuth","status":"na","category":"auth"},{"id":"auth.cimd","detail":"no remote uses OAuth","status":"na","category":"auth"},{"id":"auth.secret_in_url","detail":"no templated URL","status":"na","category":"auth"},{"id":"tools.descriptions","detail":"every tool has a description","status":"pass","category":"hygiene"},{"id":"tools.description_length","detail":"4 tools have descriptions over 1,024 characters, which crowds the context","status":"warn","category":"hygiene"},{"id":"tools.schemas","detail":"every tool has an object input schema","status":"pass","category":"hygiene"},{"id":"tools.annotations","detail":"5 of 5 tools declare readOnlyHint or destructiveHint","status":"pass","category":"hygiene"},{"id":"tools.directory_hints","detail":"every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint","status":"pass","category":"hygiene"},{"id":"tools.token_cost","detail":"about 3,455 tokens to load every tool","status":"pass","category":"hygiene"},{"id":"tools.api_dump","detail":"tools are not a one-to-one API dump","status":"pass","category":"hygiene"},{"id":"stability.changes","detail":"3 tool changes in 30 days","status":"pass","category":"stability"},{"id":"stability.rug_pull","detail":"no tool changed its meaning under the same name","status":"pass","category":"stability"},{"id":"deps.known_vulns","detail":"no npm or PyPI package","status":"na","category":"dependencies"},{"id":"deps.mcp_sdk_version","detail":"no npm or PyPI package","status":"na","category":"dependencies"},{"id":"deps.resolvable","detail":"no npm or PyPI package","status":"na","category":"dependencies"}],"drivers":["~protocol.modern","~tools.description_length"],"flags":[],"tool_count":5,"token_estimate":3455,"tools_hash":"fabebedbcc7c70be44ce521103df0c84","tools_changed_at":"2026-10-09T03:16:14.048Z","computed_at":"2026-10-10T02:27:51.671Z","disclaimer":"Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed."},"dev.protogrid/identity":{"canonical_id":"ai.zairalabs/guide","aliases":[],"alias_count":0,"repository_key":null,"owner":{"verified":false,"method":null,"since":null}}},"next_actions":[{"action":"list_tools","description":"Every current tool with input schemas","href":"/v1/servers/ai.zairalabs%2Fguide/tools","arguments":{"name":"ai.zairalabs/guide"}},{"action":"get_connection","description":"Minimal connection block for the preferred remote or package","href":"/v1/servers/ai.zairalabs%2Fguide/connection?target=mcpServers","arguments":{"name":"ai.zairalabs/guide","target":"mcpServers"}},{"action":"search","description":"Find other servers by intent","href":"/v1/search?q={query}","arguments":{"q":"{query}"}}]}
