ImmigrationDB MCP
Read-only Model Context Protocol server for ImmigrationDB, a sourced migration reference: 39 countries and 27,000+ cities, visa and residence routes, passport entry answers, cost of living, salaries, crime, air quality and climate. Every value carries its source, observation date and geographic grain. The server reads the same release as the website.

This repository holds the public contract of the hosted server: client
configuration, the tool list with input schemas (tools.json),
registry metadata (server.json) and a dependency-free smoke
test. The service runs only as the hosted endpoint above; its data release is
several gigabytes and is published as files at
https://immigrationdb.com/data/mcp/.
Tools
| Tool | Arguments | What it does |
|---|---|---|
search_destinations | query, limit, cursor | Search countries and cities. |
resolve_city | query, limit | Resolve a city name to ranked candidates; never picks an ambiguous country silently. |
get_city | country, slug, detail, metric_ids | One city with claim-level facts and source metadata. |
get_city_fact | country, slug, metric_id | Exactly one fact: value, unit, grain, dates, source. |
compare_cities | cities, metric_ids | Compare cities on compatible metrics, with provenance for every cell. |
search_facts | countries, filters, sort_metric, sort_order, limit, cursor, diagnostic | Numeric filters over city facts with explicit counts. |
list_metrics | country, block, query, comparison_eligible, limit, cursor | Metric definitions and their coverage. |
list_blocks | country, limit, cursor | Metric blocks with coverage. |
get_country | cc | One country record with official visa-route links. |
search_visa_routes | destination, purpose, limit, cursor | Visa and residence routes of a destination. |
get_legal_route | destination, route_id | One route with its official source. |
search_entry_rules |
Optional arguments are listed with the required ones; tools.json has the full
input schemas. Country arguments are ISO 3166-1 alpha-2 codes (de, lv, us); city
arguments are canonical slugs (berlin), not display names. All tools are
annotated read-only and idempotent.

{ "tool": "get_city_fact", "arguments": { "country": "de", "slug": "berlin", "metric_id": "population_total" } }
{ "tool": "compare_cities", "arguments": { "cities": [{ "country": "de", "slug": "berlin" }, { "country": "de", "slug": "munich" }], "metric_ids": ["population_total"] } }

Response contract
Every response carries the snapshot ID, its generation date and the canonical origin. Facts keep their value, unit, geographic grain, observation date, verification date, source ID, source URL and grade. Unknown or withheld values are returned as such and never estimated. Errors name the requested identifier and the snapshot ID. Rate limits and response-size caps apply per client.
Smoke test
Node 20 or newer, no install step:
node scripts/smoke.mjs # initialize, list tools, run six example calls
node scripts/smoke.mjs --write-tools # also refresh tools.json from the live server
