AnythingMCP vs Composio — which MCP gateway should you choose

How AnythingMCP and Composio differ on self-hosting, SOAP/database support, governance, and pricing. Concrete decision framework, not marketing.

Composio is the closest direct competitor to AnythingMCP in 2026. Both are MCP gateways. Both ship with adapter catalogs. Both target developers building AI agents. They differ on deployment model, API breadth, and license.

TL;DR

  • Pick Composio if you want a fully managed, US-hosted gateway with the largest adapter catalog (250+) and don't need self-hosting or legacy-protocol support.
  • Pick AnythingMCP if you need self-hosting, SOAP/WSDL support, direct database connectors, flat-rate pricing that doesn't scale per AI call, or you're in EU and need data residency.

Side-by-side

| | AnythingMCP | Composio | |---|:---:|:---:| | Self-hosted (Docker, K8s, Railway, DO) | ✅ | Limited | | EU data residency / on-prem | ✅ | US cloud primary | | Source-available code | ✅ BSL-1.1 → Apache 2.0 (2030) | Mixed (SDK open, gateway closed) | | SOAP / WSDL | ✅ Built-in parser | ❌ | | Direct DB connectors (PG/MySQL/MSSQL/Oracle/Mongo/SQLite/MariaDB) | ✅ Native | Via 3rd-party only | | OpenAPI / Postman / WSDL / GraphQL import | ✅ All four | OpenAPI only | | Adapter catalog | 29 (DACH-strong: DHL, DATEV, Weclapp, Personio, Handelsregister, VIES, Bundesbank, OpenPLZ) | 250+ (US SaaS-strong) | | MCP-to-MCP bridge | ✅ | Limited | | OAuth2 PKCE + Client Credentials | ✅ Both | ✅ Both | | RBAC tool-whitelisting | ✅ | Partial | | Audit log per tool call | ✅ | ✅ | | Per-user MCP API keys | ✅ With usage tracking | ✅ | | Pricing | Free self-host; €19/mo Starter Cloud; €149/mo Business | Free tier + per-action pricing scaling with usage |

Where Composio wins

  • Adapter count and freshness. 250+ SaaS connectors. New ones ship weekly. If you need Linear/Notion/Slack/Asana/GitHub/Trello tightly polished, Composio is hard to beat.
  • Polished agent SDKs. Composio has well-loved Python and TypeScript SDKs for embedding their gateway in agentic frameworks. AnythingMCP exposes raw MCP — you talk to it like any other MCP server.
  • Pre-built tool descriptions tuned for LLM use. Composio's adapters have been A/B-tested against Claude/GPT call patterns. Their tool descriptions are crafted, not auto-generated.
  • Network effects. Composio is the default "AI agent gateway" for many YC-backed startups. Hiring/team familiarity matters.

Where AnythingMCP wins

1. Self-hosting is a first-class deployment, not an afterthought

AnythingMCP ships as a Docker compose stack. git clone && ./setup.sh and you're running. Caddy reverse proxy with automatic Let's Encrypt SSL is built in. We test the self-hosted path on every release with the same rigour as the Cloud path.

If your security/compliance team needs to see the gateway running inside your VPC, this is a 10-minute conversation, not a 6-week procurement cycle.

2. Legacy protocols actually work

Many "modern" gateways quietly drop you when you mention SOAP. AnythingMCP parses WSDL with first-class support and generates one MCP tool per SOAP operation. We use it ourselves for banking middleware, .NET WCF services, and German tax-software ERPs.

Same for direct database connectors. Composio expects you to wrap your DB in a REST API first; AnythingMCP just talks to your database.

3. Source-available with a hard conversion date

Composio's gateway is closed-source. Their SDKs are open, but if Composio gets acquired, end-of-lifed, or pivots away, your gateway logic disappears with them.

AnythingMCP is BSL-1.1: every line of gateway code is in github.com/HelpCode-ai/anythingmcp. You can fork it. You can self-host it forever. And on 2030-03-04 the license automatically converts to Apache 2.0 — written into the license, not a verbal promise.

4. Predictable cost

Composio's free tier is generous, but per-action pricing kicks in fast at AI-agent scale (one conversation = 10-50 tool calls). At 100 daily users, the bill is meaningful.

AnythingMCP self-hosted: pay your VPS bill (~€20/mo for a small stack). Cloud: flat €149/mo for unlimited connectors and unlimited MCP servers up to 5 users — no per-call surcharge.

5. EU footprint

Built and hosted in Freiburg, Germany. GDPR-native. The 29 pre-built adapters lean heavily on DACH SaaS (DATEV, Weclapp, Personio, Handelsregister, Bundesbank, NINA, OpenPLZ, ImmobilienScout24). If your business is EU-rooted, this catalog is a much closer fit than Composio's US-leaning one.

Decision framework

Answer these in order — first "yes" tells you which:

  1. Need self-hosted / on-prem / EU data residency? → AnythingMCP
  2. Need SOAP/WSDL or direct DB connectors? → AnythingMCP
  3. >50% of your stack is US SaaS (Slack, Linear, Notion, GitHub, Asana, Salesforce, HubSpot)? → Composio probably wins on adapter polish
  4. You're a YC-backed agentic-framework startup hiring devs already familiar with Composio SDK? → Composio
  5. Otherwise → AnythingMCP gives you more architectural flexibility and lower long-term cost

Hybrid setup

The two aren't mutually exclusive. AnythingMCP's MCP-to-MCP bridge can sit in front of a Composio endpoint as one of many tool sources. We've seen teams use AnythingMCP for legacy/internal and Composio for SaaS, unified behind the AnythingMCP gateway.
