Bumps fastmcp from 2.12.3 to 3.2.0.

Release notes

Sourced from fastmcp's releases.

v3.2.0: Show Don't Tool

FastMCP 3.2 is the Apps release. The 3.0 architecture gave you providers and transforms; 3.1 shipped Code Mode for tool discovery. 3.2 puts a face on it: your tools can now return interactive UIs — charts, dashboards, forms, maps — rendered right inside the conversation.

FastMCPApp

FastMCPApp is a new provider class for building interactive applications inside MCP. It separates the tools the LLM sees (@app.ui()) from the backend tools the UI calls (@app.tool()), manages visibility automatically, and gives tool references stable identifiers that survive namespace transforms and server composition — without requiring host cooperation.

from fastmcp import FastMCP, FastMCPApp
from prefab_ui.actions.mcp import CallTool
from prefab_ui.components import Column, Form, Input, Button, ForEach, Text
app = FastMCPApp("Contacts")
@​app.tool()
def save_contact(name: str, email: str) -> list[dict]:
db.append({"name": name, "email": email})
return list(db)
@​app.ui()
def contact_manager() -> PrefabApp:
with PrefabApp(state={"contacts": list(db)}) as view:
with Column(gap=4):
ForEach("contacts", lambda c: Text(c.name))
with Form(on_submit=CallTool("save_contact")):
Input(name="name", required=True)
Input(name="email", required=True)
Button("Save")
return view
mcp = FastMCP("Server", providers=[app])

The UI is built with Prefab, a Python component library that compiles to interactive UIs. You write Python; the user sees charts, tables, forms, and dashboards. FastMCP handles the MCP Apps protocol machinery — renderer resources, CSP configuration, structured content serialization — so you don't have to.

For simpler cases where you just want to visualize data without server interaction, set app=True on any tool and return Prefab components directly:

@mcp.tool(app=True)
def revenue_chart(year: int) -> PrefabApp:
    with PrefabApp() as app:
        BarChart(data=revenue_data, series=[ChartSeries(data_key="revenue")])
    return app

Built-in Providers

Five ready-made providers you add with a single add_provider() call:

  • FileUpload — drag-and-drop file upload with session-scoped storage

Changelog

Sourced from fastmcp's changelog.

title: "Changelog" icon: "list-check" rss: true tag: NEW

v3.1.1: 'Tis But a Patch

Pins pydantic-monty below 0.0.8 to fix a breaking change in Monty that affects code mode. Monty 0.0.8 removed the external_functions constructor parameter, causing MontySandboxProvider to fail. This patch caps the version so existing installs work correctly.

Fixes 🐞

Full Changelog: v3.1.0...v3.1.1

v3.1.0: Code to Joy

FastMCP 3.1 is the Code Mode release. The 3.0 architecture introduced providers and transforms as the extensibility layer — 3.1 puts that architecture to work, shipping the most requested capability since launch: servers that can find and execute code on behalf of agents, without requiring clients to know what tools exist.

New Features 🎉

Security Scan Results

Scan Metadata

  • Project: ASH
  • Scan executed: 2026-03-31T22:31:19+00:00
  • ASH version: 3.0.0

Summary

Scanner Results

The table below shows findings by scanner, with status based on severity thresholds and dependencies:

Column Explanations:

Severity Levels (S/C/H/M/L/I):

  • Suppressed (S): Security findings that have been explicitly suppressed/ignored and don't affect the scanner's pass/fail status
  • Critical (C): The most severe security vulnerabilities requiring immediate remediation (e.g., SQL injection, remote code execution)
  • High (H): Serious security vulnerabilities that should be addressed promptly (e.g., authentication bypasses, privilege escalation)
  • Medium (M): Moderate security risks that should be addressed in normal development cycles (e.g., weak encryption, input validation issues)
  • Low (L): Minor security concerns with limited impact (e.g., information disclosure, weak recommendations)
  • Info (I): Informational findings for awareness with minimal security risk (e.g., code quality suggestions, best practice recommendations)

Other Columns:

  • Time: Duration taken by each scanner to complete its analysis
  • Action: Total number of actionable findings at or above the configured severity threshold that require attention

Scanner Results:

  • PASSED: Scanner found no security issues at or above the configured severity threshold - code is clean for this scanner
  • FAILED: Scanner found security vulnerabilities at or above the threshold that require attention and remediation
  • MISSING: Scanner could not run because required dependencies/tools are not installed or available
  • SKIPPED: Scanner was intentionally disabled or excluded from this scan
  • ERROR: Scanner encountered an execution error and could not complete successfully

Severity Thresholds (Thresh Column):

  • CRITICAL: Only Critical severity findings cause scanner to fail
  • HIGH: High and Critical severity findings cause scanner to fail
  • MEDIUM (MED): Medium, High, and Critical severity findings cause scanner to fail
  • LOW: Low, Medium, High, and Critical severity findings cause scanner to fail
  • ALL: Any finding of any severity level causes scanner to fail

Threshold Source: Values in parentheses indicate where the threshold is configured:

  • (g) = global: Set in the global_settings section of ASH configuration
  • (c) = config: Set in the individual scanner configuration section
  • (s) = scanner: Default threshold built into the scanner itself

Statistics calculation:

  • All statistics are calculated from the final aggregated SARIF report
  • Suppressed findings are counted separately and do not contribute to actionable findings
  • Scanner status is determined by comparing actionable findings to the threshold
