Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 38 | 7.6 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 76 | 12.3 | | Agent ergonomics | 13% | 16.2 | 84 | 13.7 | | Security & auth | 14% | 17.5 | 60 | 10.5 | | Payments & pricing | 10% | 12.5 | 40 | 5.0 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 85 | 7.4 | | Transparency & trust (editorial 55, provenance 85) | 7% | 8.8 | 70 | 6.1 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **62.7 → B** | ### Why each score - Reliability 38 (checked 2026-11-03): Read with the hosted lines. No status page was found; status.ipinfo.io does not resolve and the site, docs and llms.txt link none (0). No readable history (5). Limits are published with numbers, Lite unlimited, Core 150,000 and Max 250,000 requests a month, with no per-second cap (15). A 429 is documented in the OpenAPI document and the developer page for the monthly quota, and the MCP server maps it to RATE_LIMITED, but no Retry-After or backoff guidance was found; every call is a read (8 of 15). No SLA; the terms supply the service as is and as available (0). The API and the MCP server are generally available (10). 0 + 5 + 15 + 8 + 0 + 10 = 38. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 76 (checked 2026-11-03): The surface graded is the REST API, with the hosted MCP server noted. A public OpenAPI 3.0 document with 48 operations, and the MCP tools carry JSON Schema inputs (25). llms.txt and llms-full.txt, and every developer page is served as Markdown (10). Each tier page says what it returns and which plan unlocks it, and the MCP tool descriptions say which tiers each option needs, with little on when not to call (14 of 20). Schemas and examples on most responses, path parameters typed, but 401 is undocumented and some operations lack the 429 response (11 of 15). Examples in several languages on every page; only 429 is documented as an error, with no error body shape (9 of 15). A new API system since 2025 with the legacy one kept, but no public changelog, no version in the path and the OpenAPI document at 1.0.0 (7 of 15). 25 + 10 + 14 + 11 + 9 + 7 = 76. - Agent ergonomics 84 (checked 2026-11-03): Field paths such as /country return one value, the Lite and lookup objects are small, and the MCP server has six compact tools with a per-session cache (23 of 25). Batch takes up to 1,000 lookups with filter=1 to drop empty results; no pagination is needed on single lookups, and ASN and range responses have no size control (16 of 20). The only documented error is 429; the MCP server returns coded errors with a message and a suggestion (12 of 20). Every call is a read, batch is a read over POST, and the MCP tools carry tool annotations (18 of 20). One parameter per call, sensible defaults and official SDKs in eleven languages (15). 23 + 16 + 12 + 18 + 15 = 84. - Security & auth 60 (checked 2026-11-03): One access token per account, accepted as a Bearer header, HTTP Basic or a token query parameter, with no scopes found; the hosted MCP server adds OAuth with short-lived tokens (20 less 10 for the query string, plus 4 for OAuth on the MCP server, so 14). Every endpoint is a read and tools return ACCESS_DENIED outside the plan, but there is no read-only or restricted token (16 of 20). Responses are structured network data rather than third-party free text (10 of 15). The dashboard shows request graphs and lookup history per the pricing page, with no per-call log documented (8 of 15). security.txt valid until 21 August 2027 with a PGP key, a SECURITY.md with 2-day acknowledgement and a 90-day disclosure window, no bug bounty or certification found beyond a bank-grade claim (12 of 20). 14 + 16 + 10 + 8 + 12 = 60. - Payments & pricing 40 (checked 2026-11-03): No x402, MPP or L402 (0). Plan prices and per-1,000 overage rates are public on the pricing page (20). Lite is free with no card and no request cap (20). The token comes from the dashboard after a browser signup, and no key API was found (0). 0 + 20 + 20 + 0 = 40. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 85 (checked 2026-11-03): Read as a closed service with an official MCP server and SDKs. MCP server v0.2.3 on 29 October 2026, a commit on 3 November, and SDK repositories pushed in October and November (30). Eight MCP releases since 8 September 2026, v0.1.12 to v0.2.3 (20). GitHub releases for the MCP server, a community forum, a help centre and a support form, but no changelog for the API and GitHub issue pages could not be read (10 of 15). The MCP server is in the official registry as io.github.ipinfo/mcp and the SDKs are official (15). The MCP package has tests, CI with pinned actions, CodeQL and Scorecard workflows and a lock file (10). 30 + 20 + 10 + 15 + 10 = 85. - Transparency & trust 70 (checked 2026-11-03): A closed service with clear terms naming IPinfo Inc. and the governing law, with the MCP server and SDKs under Apache-2.0 (17 of 30). The privacy policy of 29 October 2026 lists processors, links a DPA and says data is kept as long as needed, with no periods (16 of 30). No deprecation policy; the legacy API is maintained for existing users with no end date (6 of 20). Processors named and hosting in the United States (16 of 20). 17 + 16 + 6 + 16 = 55. Fix list, everything this grade says the listing lacks, the biggest gain first (17 items). What it covers is at https://www.anchorterminal.com/fixes/ipinfo.md (JSON https://www.anchorterminal.com/fixes/ipinfo.json).

Call `https://api.ipinfo.io/lite/{ip}` with `Authorization: Bearer` on a free token; `/lookup/{ip}` and `detailed=true` in the MCP tools return ACCESS_DENIED without a paid plan 2. Batch up to 1,000 addresses in one POST to `/batch/lite` or `/batch` with `filter=1`; each address counts as one request against the monthly quota 3. Append a field path such as `/country` or `/asn` to get a single plain-text value instead of the full object 4. On a 429 the monthly plan quota is spent; there is no Retry-After, so stop and report rather than retry 5. Treat the data as licensed for internal use; selling or reselling it needs IPinfo's written consent under the terms ## Connect Install: ```bash uvx ipinfo-mcp-server ``` First request: ```bash curl -H "Authorization: Bearer $IPINFO_TOKEN" https://api.ipinfo.io/lite/8.8.8.8 ``` Claude Code: ```bash claude mcp add --transport http ipinfo https://mcp.ipinfo.io/ ``` MCP client configuration: ```json { "mcpServers": { "ipinfo": { "url": "https://mcp.ipinfo.io/" } } } ``` Through letme: https://letme.dev/ipinfo. letme answers with the pick and how to call it direct.

The badge or a plain link to this page verifies the listing, from a page on ipinfo.io or one of its subdomains, or the README at the root of github.com/ipinfo/mcp. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "ipinfo", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
