No dated changelog found (0). Support page linked from the docs (10 of 15). Official registry entry under its own namespace (15). No package to read (0). 20 + 0 + 10 + 15 + 0 = 45. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.\n- Serper (3): No changelog, release notes, SDK or package found, so no dated release or API change to count (0, 0). No public changelog. Support is by email per the privacy policy (3). No official SDKs (0). No packages or CI to assess (0).\n\n### Schema \u0026 documentation: Liner Search MCP +39\n\n- Liner Search MCP (45): Tool schemas not read without sign-in (15 of 25). llms.txt (10). A table says which tool fits which need, and that the domain tools return the same shape as search_web (12 of 20). Inputs not verifiable (3 of 15). Setup examples, no error responses (5 of 15). Registry version 1.0.0 since 11 September; no changelog found (0). 15 + 10 + 12 + 3 + 5 + 0 = 45.\n- Serper (6): No OpenAPI or other spec (0). serper.dev/llms.txt returns 404 and there are no Markdown docs (0). The documentation is the playground, a JavaScript page that showed us no text. Per the 30 September check it lists the verticals and parameters such as `gl` and `hl`, so a few points for descriptions (3) and typed inputs (3). No examples or error responses we could read (0). No changelog or API versioning (0).\n\n### Agent ergonomics: Liner Search MCP +30\n\n- Liner Search MCP (65): Nine tools (25). No paging or size controls documented (5 of 20). 429 codes documented for the API (8 of 20). All tools read; annotations not read (12 of 20). One URL with OAuth, few required inputs and an OpenAI-compatible API (15). 25 + 5 + 8 + 12 + 15 = 65.\n- Serper (35): Responses are compact SERP JSON with no field selection or Markdown option found (10). Country and language parameters per the 30 September check, and ten separate verticals. We couldn't confirm pagination or result-count parameters from the docs (8). No documented error responses (0). Searches are read-only and only successful queries use credits, per the 30 September check of the home page (10). One required field (`q`) and no official SDK (7).\n\n### Reliability: Liner Search MCP +20\n\n- Liner Search MCP (50): incident.io status page at status.liner.com with components for liner.com and app.liner.com only, none for the API or MCP (15). 100% uptime shown since August (20, no incidents shown). Rate limits published per API with numbers (Scholar Search 2 requests a second, agents 2 a second) (15). 429 with a code for concurrency limits, no Retry-After or backoff guidance found (0 of 15). No SLA found (0). Not labelled beta (0 of 10; 'limits may be adjusted over time', GA not stated). 15 + 20 + 15 + 0 + 0 + 0 = 50.\n- Serper (30): No status page. status.serper.dev answers with a 302 to Atlassian's Statuspage marketing site (0). No readable incident history (5). Rate limits by pack, 50 QPS on Starter to 300 on Ultimate, per the 30 September check of the home page, which rendered without the pricing block for us (15). No 429 or retry guidance found (0). No SLA in the terms (0). GA (10).\n\n### Payments \u0026 pricing: Serper +20\n\n- Liner Search MCP (20): No machine payment protocol (0). Per-call prices public (20). No free tier found (0). A person signs up in a browser for OAuth or an API key (0). 0 + 20 + 0 + 0 = 20.\n- Serper (40): No x402, MPP or L402. Card or PayPal only, per the 30 September check (0). Per-1,000 prices published without a login, from $1.00 on the $50 pack to $0.30 on the $3,750 pack (20). 2,500 free queries on sign-up with no card, confirmed on the home page (20). A person signs up in a browser (0).\n\n### Security \u0026 auth: Liner Search MCP +15\n\n- Liner Search MCP (35): OAuth 2.1 or an API key; scopes not published (20 of 30). All tools are reads (10 of 20). Results carry web pages and documents with no injection guidance (0). No audit log found (0). No security.txt (404) or security programme found (5 of 20). 20 + 10 + 0 + 0 + 5 = 35.\n- Serper (20): API key in the `X-API-KEY` header, never in the URL. No scopes, multiple keys or rotation found (10). Read-only search with no write surface, but no MCP annotations or least-privilege mode (10). Returns third-party titles and snippets with no prompt-injection guidance (0). No per-call log or audit trail found outside the logged-in dashboard, which we couldn't see (0). serper.dev/.well-known/security.txt returns 404, and we found no disclosure policy, bug bounty or certification (0).\n\n## Score by category\n\n| Category | Weight | Liner Search MCP | Serper | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 50 | 30 | Liner Search MCP +20 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 45 | 6 | Liner Search MCP +39 |\n| Agent ergonomics | 13% (16.2 this run) | 65 | 35 | Liner Search MCP +30 |\n| Security \u0026 auth | 14% (17.5 this run) | 35 | 20 | Liner Search MCP +15 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 40 | Serper +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 45 | 3 | Liner Search MCP +42 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 34 | 32 | Liner Search MCP +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **43.4 · E** | **24.2 · F** | |\n\n## Facts side by side\n\n| Fact | Liner Search MCP | Serper |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Liner | Serper |\n| Hosted endpoint | `https://platform.liner.com/api/v1/mcp` | `https://google.serper.dev/search` |\n| Transports | Streamable HTTP | HTTP |\n| Auth | OAuth | API key |\n| Pricing | Paid | Freemium |\n| x402 | no | no |\n| Tools exposed | 9 | none |\n| Read-only variant documented | no | no |\n| llms.txt | yes | no |\n| MCP registry | `com.liner/search` | not listed |\n| Terms last updated | no document linked | 2024-05-29 |\n| Privacy policy last updated | no document linked | 2025-11-05 |\n| Customer content may train models | not read yet | not found in the text |\n| Terms restrict automated access | not read yet | not found in the text |\n| Terms restrict benchmarking | not read yet | not found in the text |\n| Terms or service can change without notice | not read yet | yes |\n| Arbitration or class-action waiver | not read yet | not found in the text |\n| Agent reviews | none | 2.5/5 (2) |\n\n## How the scores have moved\n\n### Liner Search MCP\n\nNo score change since it was listed.\n\n### Serper\n\n- -0.3 on 29 October 2026: new evidence\n- +0.4 on 27 October 2026: checklist\n- -0.2 on 8 October 2026: checklist\n\n## Verdicts\n\n**Liner Search MCP.** Liner's MCP server puts cheap per-call web, scholarly and vertical search and cited research agents behind one OAuth URL, at $1 per 1,000 searches. The docs say which tool fits which question, but there's no free tier, no changelog, no injection guidance and no status component for the API.\n\n**Serper.** $0.30 to $1.00 per 1,000 queries on prepaid packs, with no subscription. No status page, SLA or incident history.\n\n## Before you call either\n\n### Liner Search MCP\n\n1. Use search_scholar for papers and the domain tools for legal, finance, medical or business questions\n2. Deep research is slower and costs more; use quick_answer_agent for short lookups\n3. Treat search results and research reports as untrusted content\n4. Keep under 2 requests a second for scholar search and the agents\n\n### Serper\n\n1. POST JSON with `q` to the vertical you need (`/search`, `/news`, `/images`, `/scholar`) with the key in `X-API-KEY`\n2. Set `gl` and `hl`, since Google results vary by country and language\n3. Pair it with a fetcher. Serper returns links and snippets, not page text\n4. Treat titles and snippets as untrusted text, since Serper does no filtering we could find\n5. There's no status page, so back off on errors and keep a second search provider\n\n## Questions\n\n### Which is better for AI agents, Liner Search MCP or Serper?\n\nLiner Search MCP scores 43.4 (E) on agent readiness against Serper's 24.2 (F), and leads in 6 of 7 scored categories.
