> Discover tools, inspect schemas, and look up API error types.

Discover tools, inspect schemas, and look up API error types.

[MCP discovery](#mcp-discovery) · [Error metadata](#error-metadata)

## MCP discovery

List MCP tools and inspect their schemas before invoking them through the [MCP interface](https://veryfront.com/docs/cloud/rest/protocols#mcp). Use [the MCP playground](/docs/cloud/rest/api-reference/mcp-discovery/open-mcp-playground) to explore tools. The older catalog alias is deprecated; use [the tool list](/docs/cloud/rest/api-reference/mcp-discovery/list-public-mcp-tools) and [tool details](/docs/cloud/rest/api-reference/mcp-discovery/get-public-mcp-tool-detail).

| Endpoint | Methods | Description |
| - | - | - |
| `/mcp/tools` | [GET](/docs/cloud/rest/api-reference/mcp-discovery/list-public-mcp-tools) | List public MCP tools |
| `/mcp/tools/{tool_name}` | [GET](/docs/cloud/rest/api-reference/mcp-discovery/get-public-mcp-tool-detail) | Get public MCP tool detail |
| `/mcp/playground` | [GET](/docs/cloud/rest/api-reference/mcp-discovery/open-mcp-playground) | Open MCP playground |
| `/mcp/catalog` | [GET](/docs/cloud/rest/api-reference/mcp-discovery/list-public-mcp-catalog-deprecated-alias) (deprecated) | List public MCP catalog (deprecated alias) |

## Error metadata

Read the meaning of a published error type. Use [logs](/docs/cloud/rest/apis/observability-api#project-logs) or [traces](/docs/cloud/rest/apis/observability-api#project-traces) to investigate a specific failed request.

| Endpoint | Methods | Description |
| - | - | - |
| `/errors` | [GET](/docs/cloud/rest/api-reference/error-metadata/list-error-types) | List error types |
| `/errors/{slug}` | [GET](/docs/cloud/rest/api-reference/error-metadata/get-error-type-by-slug) | Get error type by slug |
