Why the edge:
- Security & auth, Composio (API + MCP) +39: Composio (API + MCP) 84 (Scoped project keys split session management from session execution, read-scoped keys work for tool operations since 21 September 2026, keys take per-key IP all…); SandBase 45 (Standard keys (`sk-` and 64 hex characters) act for one organisation with no user-selectable scopes, can carry an expiry and a spending limit, are shown once an…)
- Transparency & trust, Composio (API + MCP) +35: Composio (API + MCP) 83 (SDKs and CLI are MIT on GitHub, the platform is hosted and closed under Sampark Inc's terms (20).); SandBase 48 (The editorial half.)
- Maintenance & community, Composio (API + MCP) +25: Composio (API + MCP) 93 (Python SDK 0.31.0 and TypeScript @composio/core 0.28.0 on 3 November 2026, per the changelog, the PyPI feed and npm, whose latest tag now points at 0.28.0 (30).); SandBase 68 (Read for a hosted service with an open CLI and SDKs.)
- Payments & pricing, Composio (API + MCP) +20: Composio (API + MCP) 60 (No x402, MPP or L402 (0).); SandBase 40 (No x402, MPP or L402 on the home page, pricing, billing, llms.txt or the OpenAPI paths; the balance is funded through Stripe or Airwallex checkout (0).)
- Schema & documentation, Composio (API + MCP) +13: Composio (API + MCP) 89 (OpenAPI 3.0 for API v3.1 with 94 paths (93 on 17 October, re-read on 1 November), and a legacy v3.0 reference, with documented 400, 401, 402, 403, 404, 409, 422…); SandBase 76 (A public OpenAPI 3.1 file at www.sandbase.ai/openapi.json (SandBase API 1.0.0, server https://api.sandbase.ai), linked from llms.txt, covers the OpenAI, Anthrop…)
- Agent ergonomics, Composio (API + MCP) +9: Composio (API + MCP) 90 (Composio Connect exposes seven meta-tools that search, fetch schemas, run tools in parallel and manage connections, and sessions can load only chosen toolkits…); SandBase 81 (Read on the MCP tools, with the HTTP API where a line covers it.)
