Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Unsafe deserialization swapi-app/src/main/java/com/eldermoraes/seo/SeoSiteFile.java:118, swapi-app/src/main/java/com/eldermoraes/seo/ssr/OpenApiDocs.java:82, swapi-app/src/main/java/com/eldermoraes/mcp/RecordExpansion.java:287 и ещё 1

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

sw_get

Gets one Star Wars entity by numeric record id and returns it as a JSON object. Take the id from the end of an entity's url field (from sw_search, sw_list or a relation URL). Ids are record ids, not episode numbers: FILMS id 1 is A New Hope (Episode IV). An unknown id returns a tool error, e.g. 'No films found with id 99'. Pass expand to get related records in the same call, e.g. ["homeworld", "species"]; name only the relations you need; * on a film can pass 50 KB.

sw_list

Lists every entity of one Star Wars resource type as a JSON array (Episodes I-VI data). Responses are large (all 82 PEOPLE, about 38 KB); to find a single entity, prefer sw_search, then sw_get; for a compact index pass fields, e.g. ["name"] (about 5 KB).

sw_search

Start here. Finds Star Wars entities by name (title for FILMS) with a case-insensitive substring match: 'sky' finds Luke, Anakin and Shmi Skywalker. Returns a JSON array of full entities; an empty array [] means no match; pass fields to shorten each entity. The id to pass to sw_get is the last segment of each entity's url field. Data covers Episodes I-VI only.

random

sw_random

Returns one random Star Wars entity of the given resource type as a JSON object. Each call can return a different entity, so it is not idempotent. Useful for demos and quizzes; to fetch a specific entity use sw_search or sw_get.

Star Wars API & MCP server (swapi.build) — questions

Answers built from our own checks of this server.

What can Star Wars API & MCP server (swapi.build) do?

It exposes 4 tools, read directly from the server on our last check. Among them: sw_get, sw_list, sw_random, sw_search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Star Wars API & MCP server (swapi.build) working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 723 ms. The bar chart above shows every period we have measured.

How do I connect Star Wars API & MCP server (swapi.build)?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Star Wars API & MCP server (swapi.build) need an API key?

No. Star Wars API & MCP server (swapi.build) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Star Wars API & MCP server (swapi.build)?

It answers our handshake in 723 ms on average, which is faster than 12% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Star Wars API & MCP server (swapi.build) open source?

The code is open source: it is published under the Apache-2.0 licence, written in Java, 4 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at swapi.build, which runs on its operator's own terms.
