Executor bridges PostHog MCP gaps
Rhys Sullivan showed Executor handling a PostHog workflow that PostHog’s MCP server did not expose, by feeding it the product’s OpenAPI spec instead. It’s a clean example of Executor’s pitch: normalize MCP, OpenAPI, and GraphQL into one agent-facing execution layer.
Executor’s real value is not just protocol support; it’s turning messy API surfaces into a single tool catalog agents can actually use.
- –The PostHog example highlights a common MCP pain point: partial coverage that forces humans to fall back to docs and glue code
- –Pointing Executor at an OpenAPI spec avoids waiting for bespoke MCP coverage and immediately expands the callable surface
- –Its permission model matters as much as its discovery layer, since reads can be auto-run while writes stay gated
- –The abstraction is most compelling for teams, where auth, policy, and tool access need to live outside prompt-level hacks
- –This is infrastructure for agent reliability, not another agent app
