Corsair verdict
Corsair is the right pick for TypeScript developers who want to ship third-party integrations into an AI agent or SaaS product without writing OAuth plumbing from scratch. Its flat pricing and unlimited tool calls give it a real cost edge over usage-metered rivals as agent call volume grows, but the project is pre-seed, early-stage, and thin on independent reviews, so teams with compliance or SLA requirements will find the trust record too short. If you need a no-code workflow layer rather than an in-code SDK, look at Orkas instead.
Strengths
Flat $200/month Pro plan with unlimited tool calls, connections, and team members means agent-heavy workloads do not generate surprise bills as call volume grows.
Full SDK is Apache 2.0 licensed and self-hostable at no cost with every feature included, no gated tier between free and full-featured.
Weaknesses
The project is pre-seed with roughly one full-time employee and no published SLA, compliance certifications, or documented enterprise support options, which makes it a hard sell in any procurement process that requires vendor accountability.
The Hobby plan's 50-connection and 3-team-member caps are tight enough that a small startup with more than a handful of users or developers will hit the ceiling quickly and face a jump straight to $200/month with no intermediate tier.
MCPGRAM verdict
MCPGRAM is the right pick for an independent developer or small team who wants one place to manage OAuth connections and external MCP servers across multiple agent clients without wiring each client separately. Compared to Composio, which offers 100K free tool calls and a larger connector library, MCPGRAM's free tier caps at 25K runs and 20 native connectors, so heavy users will hit limits faster. Teams that need SSO, SCIM, or audit-grade compliance today should look elsewhere; those features are listed as 'Soon' even on the Custom tier.
Strengths
Free Hobby plan includes 20 native connectors and 25K tool runs per month with no credit card, making it genuinely usable for side projects without a trial clock.
Universal layer architecture means one OAuth connection serves Claude Code, Cursor, Codex, Windsurf, and Cline simultaneously, eliminating per-client credential duplication.
Weaknesses
SSO, SCIM provisioning, DPA, and VPC deployment are all listed as 'Soon' even on the Custom enterprise tier, meaning any team with compliance or identity management requirements cannot use MCPGRAM today regardless of budget.
Billing for paid plans processes through Razorpay in INR, which introduces currency conversion friction and potential card-decline issues for buyers outside India who expect straightforward USD Stripe billing.
