### Timeout
|
||||
|
||||
You can set a timeout for all API requests:
|
||||
You can set a timeout for all requests by providing a `timeout` parameter (in seconds):
|
||||
|
||||
```python
|
||||
# Set a 5 second timeout for all requests
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
timeout=5.0
|
||||
client=api_client,
|
||||
timeout=30.0 # 30 second timeout
|
||||
)
|
||||
```
|
||||
|
||||
This timeout is applied to all requests made by tools, resources, and resource templates.

||||

||||
## Route Mapping

<VersionBadge version="2.5.0" />

By default, OpenAPI routes are mapped to MCP components based on these rules:

@ -54,7 +53,6 @@ By default, OpenAPI routes are mapped to MCP components based on these rules:
|
|||
| `GET` with path params | `GET /users/{id}` | Resource Template | Path parameters become template parameters |
|
||||
| `POST`, `PUT`, `PATCH`, `DELETE`, etc. | `POST /users` | Tool | Operations that modify data |
|
||||
|
||||
|
||||
Internally, FastMCP uses a priority-ordered set of `RouteMap` objects to determine the component type. Route maps indicate that a specific HTTP method (or methods) and path pattern should be treated as a specific component type. This is the default set of route maps:

### Custom Route Maps
|
||||
|
||||
#### Custom Route Maps
|
||||
|
||||
Users can add custom route maps to override the default mapping behavior. User-supplied route maps are always applied first, before the default route maps.
|
||||
|
||||
```python
|
||||
from fastmcp.server.openapi import RouteMap, RouteType
|
||||
from fastmcp.server.openapi import RouteMap, MCPType
|
||||
|
||||
# Custom mapping rules
|
||||
custom_maps = [
|
||||
# Force all analytics endpoints to be Tools
|
||||
RouteMap(methods=["GET"],
|
||||
pattern=r"^/analytics/.*",
|
||||
route_type=RouteType.TOOL)
|
||||
mcp_type=MCPType.TOOL)
|
||||
]
|
||||
|
||||
# Apply custom mappings
|
||||
mcp = await FastMCP.from_openapi(
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
route_maps=custom_maps
|
||||
)
|
||||
```
|
||||
|
||||
<Info>
|
||||
For backward compatibility, FastMCP still supports the `route_type` parameter and `RouteType` enum, but they are deprecated and will be removed in a future version. You will see deprecation warnings if you use them.

### All Routes as Tools
|
||||
#### All Routes as Tools
|
||||
|
||||
When building AI agent backends, it's often useful to treat all routes as callable tools regardless of their HTTP method. You can use the `all_routes_as_tools` parameter to automatically map every route to a Tool:
|
||||
When building AI agent backends, it's often useful to treat all routes as callable tools regardless of their HTTP method. You can use the `ALL_TOOLS()` shortcut or create a custom route map:
|
||||
|
||||
```python
|
||||
# Make all endpoints tools, regardless of HTTP method
|
||||
# Make all endpoints tools using the shortcut
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
all_routes_as_tools=True
|
||||
route_maps=[ALL_TOOLS()]
|
||||
)
|
||||
```
|
||||
|
||||
This is equivalent to defining a single route map that matches all routes:
|
||||
|
||||
```python
|
||||
# Same effect as all_routes_as_tools=True
|
||||
# Same effect using a custom route map
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
route_maps=[
|
||||
RouteMap(methods="*", pattern=r".*", route_type=RouteType.TOOL)
|
||||
RouteMap(methods="*", pattern=r".*", mcp_type=MCPType.TOOL)
|
||||
]
|
||||
)
|
||||
```
|
||||
|
||||
Note that `all_routes_as_tools` and `route_maps` cannot be used together - if you need more complex mapping rules, use `route_maps` instead.
|
||||
#### Excluding Routes
|
||||
|
||||
If you want to exclude certain routes from being converted to MCP components, you can map them to `MCPType.EXCLUDE`. This is useful for endpoints that should not be accessible to the agent.
|
||||
|
||||
```python
|
||||
from fastmcp.server.openapi import RouteMap, MCPType
|
||||
|
||||
# Custom mapping rules to exclude specific routes
|
||||
custom_maps = [
|
||||
# Exclude all admin endpoints
|
||||
RouteMap(
|
||||
methods="*",
|
||||
pattern=r"^/admin/.*",
|
||||
mcp_type=MCPType.EXCLUDE
|
||||
),
|
||||
# Exclude analytics GET endpoints
|
||||
RouteMap(
|
||||
methods=["GET"],
|
||||
pattern=r"^/analytics/.*",
|
||||
mcp_type=MCPType.EXCLUDE
|
||||
)
|
||||
]
|
||||
|
||||
# Apply custom mappings
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
route_maps=custom_maps
|
||||
)
|
||||
```
|
||||
|
||||
When a route is mapped to `MCPType.EXCLUDE`, FastMCP will log its presence but won't create any MCP component for it, effectively making it invisible to clients and agents using the MCP server.
|
||||
|
||||
You can customize this behavior by providing a list of `RouteMap` objects:
|
||||
|
||||
```python
|
||||
from fastmcp.server.openapi import FastMCPOpenAPI, RouteMap, MCPType
|
||||
|
||||
# Custom route mappings
|
||||
custom_mappings = [
|
||||
# Convert all user-related routes to tools
|
||||
RouteMap(
|
||||
methods=["GET", "POST", "PUT", "DELETE"],
|
||||
pattern=r"^/users.*",
|
||||
mcp_type=MCPType.TOOL
|
||||
),
|
||||
# Exclude analytics routes
|
||||
RouteMap(
|
||||
methods=["*"], # All methods
|
||||
pattern=r"^/analytics.*",
|
||||
mcp_type=MCPType.EXCLUDE
|
||||
),
|
||||
]
|
||||
|
||||
# Create server with custom mappings
|
||||
mcp = FastMCPOpenAPI(
|
||||
openapi_spec=spec,
|
||||
client=httpx.AsyncClient(),
|
||||
route_maps=custom_mappings,
|
||||
)
|
||||
```
|
||||
|
||||
#### Route Map Shortcuts
|
||||
|
||||
|
||||
FastMCP provides several shortcut functions to create common route maps more easily:
|
||||
|
||||
```python
|
||||
from fastmcp.server.openapi import (
|
||||
ALL_TOOLS,
|
||||
EXCLUDE_ALL,
|
||||
EXCLUDE_PATTERN,
|
||||
PATTERN_AS_TOOLS,
|
||||
)
|
||||
|
||||
# Create an MCP server with custom route maps using shortcuts
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
route_maps=[
|
||||
# First exclude all admin endpoints
|
||||
EXCLUDE_PATTERN(r"^/admin/.*"),
|
||||
|
||||
# Make all /api/v1 endpoints tools
|
||||
PATTERN_AS_TOOLS(r"^/api/v1/.*"),
|
||||
|
||||
# Make all remaining routes tools
|
||||
ALL_TOOLS(),
|
||||
]
|
||||
)
|
||||
```
|
||||
|
||||
Available shortcuts:
|
||||
|
||||
| Shortcut Function | Description |
|
||||
|------------------|-------------|
|
||||
| `ALL_TOOLS()` | Converts all matching routes to tools |
|
||||
| `EXCLUDE_ALL()` | Excludes all matching routes from being converted to any component |
|
||||
| `PATTERN_AS_TOOLS(pattern)` | Converts routes matching a specific pattern to tools |
|
||||
| `EXCLUDE_PATTERN(pattern)` | Excludes routes matching a specific pattern |
|
||||
|
||||
These shortcuts are particularly useful for:
|
||||
|
||||
1. Converting all remaining unmatched routes to tools (use `ALL_TOOLS()`)
|
||||
2. Excluding whole sections of your API (use `EXCLUDE_PATTERN("/path/.*")`)
|
||||
3. Converting routes matching specific patterns to tools (use `PATTERN_AS_TOOLS("/path/.*")`)
|
||||
|
||||
<Tip>
|
||||
You can use `EXCLUDE_ALL()` as the last entry in your custom route maps to completely ignore the default route maps. Since custom route maps are applied first and default maps are appended afterward, having `EXCLUDE_ALL()` at the end of your custom maps will match any routes that your earlier custom rules didn't match, preventing the default maps from having any effect.
|
||||
|
||||
```python
|
||||
# Create server that only uses custom route maps, ignoring defaults
|
||||
mcp = FastMCP.from_openapi(
|
||||
openapi_spec=spec,
|
||||
client=api_client,
|
||||
route_maps=[
|
||||
# Routes to keep as tools
|
||||
PATTERN_AS_TOOLS(r"^/api/v1/.*"),
|
||||
|
||||
# Exclude everything else (ignores default route maps)
|
||||
EXCLUDE_ALL(),
|
||||
]
|
||||
)
|
||||
```
|
||||
</Tip>
