# /glama/servers/schema

`POST /api/glama/servers/schema`

Price: 1 credit

Get the MCP protocol schema Glama recorded when it connected to one server. Returns the protocol version the server negotiated, the capabilities it declared, its instructions text, its prompts and resources, and every tool with the input and output schema the server itself advertised plus Glama's quality tier for that tool.

## How to use it

This is the server's own introspection response, not Glama's catalog copy: use it when you need what a running instance actually reports rather than what the listing claims. Glama can only fill it for servers it managed to launch, so `capabilities`, `instructions`, `prompts` and `resources` are commonly null even on healthy servers and their absence says nothing about the server. The tool list from /glama/servers is the one to rely on when this comes back thin.

## Parameters

- `access-token` (string, required)

## Request body

- `timeout` (integer) — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
- `server` (string, required) — Glama server id in namespace/slug form, or the address of its Glama page (examples: "korotovsky/slack-mcp-server", "@korotovsky/slack-mcp-server", "https://glama.ai/mcp/servers/korotovsky/slack-mcp-server"; minLength: 1)

## Response

### 200 — Successful Response

- `url` (string, required)
- `protocol_version` (string, nullable)
- `instructions` (string, nullable)
- `capabilities` (object, nullable)
- `prompts` (array) (default: [])
- `resources` (array) (default: [])
- `tools` (array) (default: [])
  - `@type` (string) (default: "GlamaSchemaTool")
  - `name` (string, required)
  - `display_name` (string, nullable)
  - `description` (string, nullable)
  - `tier` (string, nullable)
  - `input_schema` (object, nullable)
  - `output_schema` (object, nullable)
  - `annotations` (object, nullable)

## Errors

### 422 — Validation Error

The request body did not validate

What to do: Check the fields against this schema. A URN with the wrong prefix is the most common cause.

- `detail` (array)
  - `loc` (array, required)
  - `msg` (string, required)
  - `type` (string, required)
  - `input` (any)
  - `ctx` (object)

### 408

The request ran past its time limit

What to do: Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.

### 412

No Glama server carries this namespace/slug id

What to do: Retrying will not help: either the entity does not exist, or the input points at a different one.

### 429

Too many requests: a rate limit or a usage window is exhausted

What to do: When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.

### 500

Something broke on our side

What to do: Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.

### 529

Rate limit reached, or the endpoint is overloaded

What to do: Wait at least 30 seconds, then retry.

## Response envelope

Success: Array of objects (may be empty if no results)

Error: Error may coexist with partial results if it occurs mid-execution. Check X-Error header and status code.

Every response carries these headers:

- `X-Error` — Error message text (present only on error)
- `X-Request-ID` — Unique request identifier
- `X-Execution-Time` — Execution time in seconds
- `X-Result-Count` — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
- `X-Total-Available-Results` — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
- `X-Warning` — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
- `X-Retry-After` — Seconds to wait before retrying. Present only on 429.
