Convex MCP server

# Changelog ## 1.27.3 - Convex CLI now respects `HTTPS_PROXY` / `HTTP_PROXY` environment variables. This is generally useful but was motivated by making Convex run in remote asynchronous agent environemnts like Codex. - Cutoffs for logging large and slow Transition messages have been lowered. ## 1.27.2 - `npx convex run` sends function log output to stderr instead of stdout. - Increase the timeout when waiting for a local backend to start up from 10 to 30 seconds. - Capability to provision WorkOS environments when `WORKOS_CLIENT_ID` environment variable is missing. ## 1.27.1 - Changes to logged messages in the console, where previously only WebSocket reconnection messages were logged. These can still be silenced with the `logger: false` client option. - Improved support for the TypeScript tsconfig.json compiler option "exactOptionalPropertTypes" with the convex package. - Additional WebSocket connection debugging information about Transition messages. - Clearer error messages when running codegen in preview deployments. - Token limits for especially verbose logs MCP tool. - Add (preexisting) `codegen` options to `convex.json` schema. ## 1.27.0 - Add support for configuring the Node.js version used by Node actions using the `node.nodeVersion` field of the `convex.json` file ([docs](https://docs.convex.dev/production/project-configuration#configuring-the-nodejs-version)). - `npx convex data` now supports exporting data as JSON or JSONL with the `--format` option. - `npx convex env set` now supports setting environment variables via piping (STDIN) (for example `cat keys/my-private-key.txt | npx convex env set JWT_PRIVATE_KEY`). ## 1.26.2 - Fix for pushing schemas to older (self-hosted) deployment builds. ## 1.26.0 - Add support for staged indexes. Instead of blocking on push, a staged index backfills while you push more changes to a deployment, then can be used once it is no longer marked as staged. ``` export default defineSchema({ messages: defineTable({ author: v.string(), body: v.string(), }) .index("by_author", { fields: ["author"], // watch for progress in dashboard. Once it's at 100%, remove the staged flag staged: true, }) }); ``` Read more in the docs (link coming soon). - Experimental `ConvexReactClient.prewarmQuery({query, args})` method for subscribing to a query for 5 seconds. Prewarming indicates likely future interest in a subscription and is currently implemented by subscribing to the query for 5 seconds. The return value of this method may change and the arguments may change in the future so this API should be considered unstable but adapting to these changes shouldn't be difficult. - Expose the schemaValidation property of schema, intended for runtime tests or assertions that it is indeed enabled. - Export TokenFetcher type, intended for external auth integrations. - More informative messaging on code push. Link to index backfill progress in the dashboard. - Fix a bug where an auth token passed initially to the ConvexHttpClient was ignored. - Experimental `expectAuth` option for Convex clients for indicating that setAuth() will be called soon, so to wait for that token. Once setAuth() has been called the existing token-waiting behavior takes over. This is useful for applications that create a client and run a mutation, query, or action _before_ setAuth() has been called, e.g. via a provider in React. - Change the default permissions for the local MCP server: access to production deployments is now disabled by default, requiring `--dangerously-enable-production-deployments` to enable. - Add a "logs" tool to the local MCP server. ## 1.25.4 - Experimental `convex dev --once --debug-node-apis` debug flag for tracing through imports to find Node.js APIs imported from non-"use node" convex endpoint files. - Experimental `CONVEX_AGENT_MODE=anonymous npx convex dev` for a non-interactive anonymous development flow when not logged in. - Simplify the `Logger` interface of Convex clients making it easier to replace. - Reactive `ConnectionState` via `useConvexConnectionState` hook. How often this value updates may change in the future if more information is added to `ConnectionState`. - Escape JavaScript keywords in codegen, fixing issues with files in the convex folder named things like convex/delete.ts. - Warn when the explicit value `undefined` is passed to Next.js server-side helpers, indicating the issue may have been an unset environment variable. This may become an error in the future. - Error closer to the call site when invalid validators are contructed. ## 1.25.2 - Increase a network timeout that was causing Node.js v20+ issues on slow connections, good old Happy Eyeballs https://github.com/nodejs/node/issues/54359. ## 1.25.1 - Print more error info in `npx convex network-test`. - Crash when it looks like an environment variable is missing: `CONVEX_DEPLOY_KEY=project:me:new-project|eyABCD0= npx convex` parses as `CONVEX_DEPLOY_KEY=project:me:new-project | eyABCD0='' npx convex` but when was meant was `CONVEX_DEPLOY_KEY='project:me:new-project|eyABCD0=' npx convex`. Crash when an environment variable like `ey...0=` is present to surface errors like this quicker. ## 1.25.0 To upgrade to this release you'll need to upgrade any Convex components you use. - Set `process.env.NODE_ENV = "production"` during Convex function bundling. This will result in different code being bundled from some packages, generally faster code. - Smaller bundles via esbuild minification. - ConvexHttpClient mutations are now queued by default, making the ConvexHttpClient match the behavior of ConvexClient and ConvexReactClient. This makes switching between these safer. If you need unqueued mutations (you need to run multiple mutations concurrently), pass the unqueued: true option or create a separate ConvexHttpClient for each queue of mutations you need. - Allow passing auth to ConvexHttpClient as an option in the constructor. This is appropriate for short-lived ConvexHttpClients and it more convenient for instantiating a client and using it in a single expression. - Restore check that Convex functions are not imported in the browser. Convex functions run in a Convex deployment; including their source in a frontend bundle is never necessary and can unintentionally reveal implementation details (and even hardcoded secrets). This check current causes a `console.warn()` warning, but in future versions this will become an error. If you see the warning "Convex functions should not be imported in the browser" you should address this by investigating where this is being logged from; that's code you don't want in your frontend bundle. If you really want your Convex functions in the browser it's possible to disable this warning but this is not recommended. - TypeScript error when async callbacks are passed to `mutation.withOptimisticUpdate()`: an optimistic update function is expected to run synchronously. - Experimental onServerDisconnectError() callback option for Convex clients. This is a stopgap client callback to report unusual server disconnect errors. The content of these messages, which messages trigger the callback, and the existence of the callback are all subject to change as we develop better interfaces for disconnect metrics. ## 1.24.8 - Restore short retry timer for WebSocket reconnects initiated by an error on the client. This behavior was inadvertently changed in 1.24.7. ## 1.24.7 - Increase WebSocket client timeouts in general and especially for abnormal server errors. See [this incident postmortem](https://news.convex.dev/how-convex-took-down-t3-chat-june-1-2025-postmortem/) for more context. ## 1.24.6 - Fix another bug with new Custom JWT auth support in projects that use Convex backend components. ## 1.24.5 - `ConvexClient.mutation()` now accepts a third `options` argument that can contain an optimistic update. ## 1.24.3 - Add `.url` property to ConvexReactClient. - Earlier errors when invalid objects are passed to `defineTable()`. ## 1.24.2 - Fix bug with new Custom JWT auth support in projects that use Convex backend components. - Support larger data imports from the command line by choosing larger chunk size when necessary. - Calling setAuth on a disabled ConvexClient is now an no-op. - Add `npx convex dash` alias for dashboard command. - Limit the number of nested query operators to 256. ## 1.24.1 - Accept `true` and `false` as values for logger in all clients, making disabling logs from convex functions run on a development deployment simpler: it's no longer necessary write your own no-op logger. ## 1.24.0 - Drop support for React 17 and remove use of `unstable_batchedUpdates` as React 18 introduced [Automatic batching](https://react.dev/blog/2022/03/29/react-v18#new-feature-automatic-batching) If you use React 17 and choose to override the change in supported peer dependencies (please don't), you may notice query updates are no longer batched: it's possible for one Convex query update to occur on a different React render than another causing single frames of discrepancies in UI or worse, errors if you have code that relies on the client-side consistency like client-side joins. You may also notice nothing. Without batched updates some queries may be a few milliseconds ahead of other queries, which is still much less than the differences in other data fetching solutions, e.g. React Query or SWR, in non-batched mode. - Remove dependency on `react-dom`, making it possible to use on "React Native only" projects without overriding any dependency resolution. - New optimistic update helpers for paginated queries: three helpers `insertAtTop`, `insertAtBottomIfLoaded`, and `insertAtPosition`. - The `npx convex login --login-flow paste` flag can be used to explicitly opt into the manual token paste login method. - Fix MCP servers for self-hosted deployments: previously MCP CLI commands were attempting to contact a cloud deployment (which didn't exist) in self-hosted setups. - New `compareValues` function exported from `convex/values` which matches Convex values semantics as implemented in backends. This function should match the Rust implementation in backend (and it property-tested in pursuit of this!) but in the event of discrepancies the Rust implementation should be considered authoritative. ## 1.23.0 - `npx convex dev` now supports the option of running Convex locally without an account ## 1.22.0 - Options for turning off MCP tools and blocking prod deployments (see `npx convex mcp`) - Add `--run-sh` option to `npx convex dev`, similar to `--run` but for shell commands - Add `inflightMutations` and `inflightActions` to `convexClient.connectionState()` ## 1.21.0 - `npx convex dev` tails logs by default. See the `--tail-logs` option for more. - Improvement to the `.unique()` error message to print `_id`s [PR](https://github.com/get-convex/convex-backend/pull/59) - Fixes to avoid race conditions in auth [PR](https://github.com/get-convex/convex-js/pull/29) ## 1.20.0 - Calling registered functions directly like helper functions no longer typechecks. See release notes for 1.18.0 for more. - Upgrade esbuild for a sourcemap bug fix. - Fix FieldTypeFromFieldPath to handle union of nested values and primitives. ## 1.19.5 - `npx convex mcp start` runs an MCP server. AI agents can introspect deployment schema (both declared and inferred) and function APIs, read data from tables, call functions,and write oneoff queries in JS. ## 1.19.3 - Upgrade esbuild from 0.23 to 0.25 to address security warnings about https://github.com/evanw/esbuild/security/advisories/GHSA-67mh-4wv8-2f99 Convex does not use the development server functionality of esbuild which contains the vulnerability. ## 1.19.2 - Improved support for working with self-hosted deployments: every command that makes sense (e.g. not `npx convex login`) works with self-hosted deployments. The environment variables `CONVEX_SELF_HOSTED_URL` and `CONVEX_SELF_HOSTED_ADMIN_KEY` are now used to identity self-hosted deployments. https://github.com/get-convex/convex-backend/tree/main/self-hosted#self-hosting-convex for more. - export the `ValidatorJSON` record types. ## 1.19.0 - Support for Local Deployments, now in beta. See https://docs.convex.dev/cli/local-deployments for more. Local deployments run your Convex dev deployment for your project on your local machine, which should make syncing your code faster. It also makes resources used during development like function calls and database bandwidth free, since it's your own compute resources you're using! ## 1.18.0 - Warn on direct Convex function call. This adds a console.warn whenever a Convex Function (mutation, query, action, internalMutation, etc.) is called directly ```ts export const foo = mutation(...); export const bar = mutation({ args: v.any(), returns: v.any(), handler: (ctx, args) => { const result = await foo(); }) } ``` because this pattern causes problems and there are straightforward workarounds. The problems here: 1. Arguments and return values aren't validated despite the presence of validators at the function definition site. 2. Functions called this way unexpectedly lack isolation and atomicity. Convex functions may be writting assuming they will run as independent transactions, but running these function directly breaks that assumption. 3. Running Convex functions defined by customFunctions like triggers can cause deadlocks and other bad behavior. There are two options for how to modify your code to address the warning: 1. Refactor it out as a helper function, then call that helper function directly. 2. Use `ctx.runMutation`, `ctx.runQuery`, or `ctx.runAction()` instead of calling the function directly. This has more overhead (it's slower) but you gain isolation and atomicity because it runs as a subtransaction. See https://docs.convex.dev/understanding/best-practices/#use-helper-functions-to-write-shared-code for more. Filter to warnings in the convex dashboard logs to see if you're using this pattern. For now running functions this way only logs a warning, but this pattern is now deprecated and may be deleted in a future version. - Support for Next.js 15 and [Clerk core 2](https://clerk.com/docs/upgrade-guides/core-2/overview): `@clerk/nextjs@5` and `@clerk/nextjs@6` are now known to work to Convex. Docs, quickstarts and templates have not yet been updated. If you're upgrading `@clerk/nextjs` from v4 or v5 be sure to follow the Clerk upgrade guides as there are many breaking changes. - Improvements to `npx convex run`: - Better argument parsing with JSON5 so `{ name: "sshader" }` parses - support for `--identity` similar to dashboard "acting as user" feature, like `npx convex run --identity '{ name: "sshader" }'` - `npx convex run api.foo.bar` is equivalent to `npx convex run foo:bar` - `npx convex run convex/foo.ts:bar` is equivalent to `npx convex run foo:bar` - `npx convex run convex/foo.ts` is equivalent to `npx convex run foo:default` - Allow non-JavaScript/TypeScript files in the `convex/` directory. Only .js etc. files will be bundled and may define Convex functions points but adding a temporary file like `convex/foo.tmp` will no longer break` the build. - Fix type for FieldTypeFromFieldPath with optional objects. - Fix types when a handler returns a promise when using return value validators with object syntax. ## 1.17.4 - Revert use of the identity of useAuth from Clerk to determine whether refreshing auth is necessary. This was causing an auth loop in Expo. ## 1.17.3 - Fetch a new JWT from Clerk when using Clerk components to change the active orgId or orgRole in React on the client. Any auth provider can implement this by returning a new `getToken` function from the `useAuth` hook passed into `ConvexProviderWithAuth`. ## 1.17.2 - Revert local Prettier settings change described in 1.17.1 which removed angle brackets in some cases where local prettier config used plugins. - `npx convex import --replace-all` flag which behaves like the Restore functionality in the dashboard. ## 1.17.1 - Use local Prettier settings to format code in `convex/_generated` if found. - Extend supported react and react-dom peerDependencies to include v19 prereleases. This is temporary, only stable React 19 releases will be supported in the long term. - Hook up Sentry reporting for local deployments, opted-into by `npx convex dev --local`. This telemetry will be made configurable before this feature is released more broadly. This is being called out here for transparency regarding telemetry, but this `--local` feature is not yet ready for general consumption. Please don't use it unless you're excited to help test unfinished features and willing to have errors submitted to Convex. - Don't try to bundle .txt or .md files in the convex/ directory. - Don't include credentials in HTTP client requests. ## 1.17.0 - Disallow extra arguments to CLI commands. - `--component` flags for `convex import` and `convex data`. - `--run-component` flag for `convex dev --run` - Remove prettier-ignore-start directives from generated code. - Fix file watcher bug where a syntax error could cause a file to stop being watched. - Downgrade jwt-decode dependency back to ^3.1.2. - Change refresh token renewal timing ## 1.16.6 - Detect TanStack Start projects and use environment variable name `VITE_CONVEX_URL`. ## 1.16.5 - restore `--run` flag of `convex import` ## 1.16.4 - Don't typecheck dependent components by default, add `--typecheckComponents` flag to typecheck. ## 1.16.3 - Fix some library typecheck errors introduced in 1.16.1. Workaround for previous versions is to add `"skipLibCheck": true` to the tsconfig.json in the convex directory. ## 1.16.2 - Change some language around components beta. ## 1.16.1 - Release components, a feature in beta. These codepaths should not be active unless a convex directory contains a file named `convex.config.ts`. Components aren't documented yet and may change significantly before general release. ## 1.16.0 - Added support for a new validator, `v.record`. This is a typed key-value object in TypeScript. More information can be found in the [docs](https://docs.convex.dev/functions/validation#record-objects). - Upgrade esbuild from 0.17 to 0.23. It's possible to use an npm override to use a different version of esbuild if you need to stay on an older version, although changes to the esbuild API could break this in the future. See [esbuild changelog](https://github.com/evanw/esbuild/blob/main/CHANGELOG.md) for the full list of changes. One standout: tsconfig.json is no longer used by esbuild for `jsx` setting. Convex now sets it manually to ["automatic"](https://esbuild.github.io/api/#jsx). ## 1.15.0 - Added new command, `npx convex function-spec`, that exposes the function metadata (name, type, validators, visibility) of functions defined in your Convex deployment - Generated code no longer includes the "Generated by convex@version" comment - Fix issue with `convexClient.query()` so it always returns a Promise ## 1.14.0 - Updates to ConvexReactClient to work better with authentication and server rendering - `npx convex init` and `npx convex reinit` have been deprecated in favor of `npx convex dev --configure` - Drop support for Node.js v16, and with it drop the dependency on node-fetch. This removes the 'punycode' deprecation warning printed when running the CLI in more recent versions of Node.js. - Support for custom claims in JWTs ## 1.13.2 - Fix `npx convex import` regression in 1.13.1 ## 1.13.1 - Relax client URL validation to prepare for Convex backends accessible on arbitrary domain. This makes `skipConvexDeploymentUrlCheck` client option also no longer required for accessing deployments not hosted on the Convex BaaS. - Fix bug where the first mutation request send over the WebSocket failing would not roll back the corresponding optimistic update (completedMutationId could be 0 which is falsey!) - Fix bug where `codegen --init` would fail if no Convex directory existed yet. - Action and query function wrappers now also allow validators for args (previously only objects were accepted) and objects for returns (previously only validators were accepted). - Change `httpRouter` behavior for overlapping paths: exact matches first, then the longest prefix patch that matches. ## 1.13.0 - Convex queries, mutations, and actions now accept `returns:` property to specify a return value validator. Return value validators throw a runtime error (so will roll back the transaction in a mutation) when the value returned from a query or mutation does not match this validator. This is _stricter than TypeScript_ in that extra properties will not be allowed. - Validator fields are now exposed: the return value of `v.object({ ... })` now has a `.fields` property with the validators for each property on it. ``` const message = v.object({ user: v.string(), body: v.string() }); const imageMessage = v.object({ ...message.fields, }) ``` These validators are also exposed on the schema at `schema.tables.messages.validator` The `Validator` export is no longer a class. It is now a discriminated union type of all validators where the `.kind` as the discriminator. The `Validator` type still has three type parameters with only the first (the TypeScript type enforced by the validator) required. The second type parameter IsOptional is no longer a boolean, is it "optional" or "required" now. These are breaking changes if you're using the two optional type parameters of `Validator` or doing `instanceof` checks with `Validator`! We apologize for the inconvenience. The same users this affects should be the ones that most benefit from the ability to work with validator types more directly. - Argument validators now accept validators (object validators and union validators) in addition to objects with validators as properties. Return value validators similarly accept either validators or objects with validators as properties, but unlike `args:` any validator is allowed. Custom function wrappers (AKA middleware) should continue to work, but to present the same API has the builtin Convex function wrappers `query`, `internalQuery`, `mutation` etc. you'll need to update such code to accept either a validator or an object of validators. You'll likely want to update these anyway to support return value validators. The new `asValidator` helper maybe useful here. - The default tsconfig.json created in projects when first creating the `convex/` directory now uses `"moduleResolution": "Bundler"`. This is just a better default, you [probably never want the previous default `"node"`/`"node10"`](https://www.typescriptlang.org/tsconfig/#moduleResolution). ## 1.12.1 - Fix bug where `npx convex deploy` and `npx convex dev` would incorrectly skip pushing if the only change was removing files ## 1.12.0 - `npx convex env set` works with `ENV_VAR_NAME=value` syntax ## 1.11.3 - Fix bug when filling out an empty env file - Exclude files beginning with # from convex directory entry points - Warn when pushing with an https.ts file - throw if argument to Query.take() is not an integer ## 1.11.2 - Fix timestamps in npm convex logs ## 1.11.1 - Allow Clerk 5 (currently in beta) in convex peerDependencies - Fix typechecking bug on Windows caused by the Node.js patch for CVE-2024-27980 that makes running tsc.CMD directly no longer work - Exclude jsonl from convex directory entry points - Add autocomplete for project selection in new project flow - output debugBundlePath as full bundle instead of as a single file --- Find release notes for versions before 1.11.3 on the [Convex Blog](https://news.convex.dev/tag/releases/).
