Connectors

The connectors plugin guides setup, connection diagnostics and governed integration calls in Claude Code and Codex. It follows the current Connectors CLI, verified against v0.65.0.

Install in either host​

b10x installs the plugin and its CLI together. Select your host and review the resulting plan:

b10x init connectors --host claude --out ~/.local/state/b10x/plan.json

Use --host codex in Codex. Apply an approved plan with:

b10x setup apply --plan ~/.local/state/b10x/plan.json --yes

Since v0.48.0 each release carries checksummed prebuilt archives for x86-64 and ARM64 Linux and macOS, which setup installs by default. An older, source-only release, --method cargo or another target builds the connectors Cargo package from its exact release tag with locked dependencies and needs Rust 1.91 or newer. There is no Windows release binary; since v0.49.0 the CLI builds and runs on Windows from that source build. Credentials live in the Secret Service on Linux, the login keychain on macOS and the Credential Manager on Windows. The macOS binary is not signed yet: one downloaded through a browser needs xattr -d com.apple.quarantine connectors, and an upgraded binary cannot read keychain credentials an earlier build stored, so they are entered again. Adapter executables, configuration and credentials are separate prerequisites. Setup preserves other installed plugins and snapshots changes.

A new session loads the installed skills. In Claude Code invoke /connectors:integrating; in Codex select integrating or invoke $connectors:integrating. Both hosts load the same skill files. b10x skill connectors:integrating prints the current instructions without a reload.

First use​

Ask: “Use connectors to inspect my local Connector readiness.” The skill checks CLI availability, runs connectors --output json setup check and lists configured instances. These checks do not authenticate, start services or prove that cached metadata is current.

For an existing integration, it selects a configured instance and connection, lists operations, and describes one before invocation. The returned schema identity and revision bind the call; its JSON input must match the described schema. Invocation rechecks admission and may start the supervised local owner/adapter. Missing capability or access is reported explicitly.

Since v0.60.0 one command invokes an operation: connectors invoke <connector>[/<instance>] <operation>, with the instance, connection, schema and revision defaulting to the only ones that fit and --describe printing the description without calling anything. Since v0.63.0 --fields prints only the named members of a result, --each prints one line per array element, and --walk --out <file> follows a page sequence the operation declares, so an agent neither reads a whole result into context nor writes its own cursor loop.

For onboarding, the operator enters the credential document through protected terminal, file or stdin acquisition. The skill reads safe status, not secret values. External writes need the user's authorization and the adapter's admission, exact approval subject and protected proof. Since v0.60.0 the CLI has no command for a standalone service: a service is called over HTTP, or a local instance is given its endpoint with connections connect --endpoint. Since v0.57.0 connectors server --transport stdio is a local MCP server on Linux that offers admitted read-only operations as tools; it serves no writes, resources or prompts. Since v0.58.0 an OAuth2 profile signs in by browser or device code, and connections token hands its access token to the operator.

Upgrade​

b10x upgrade connectors --host claude --out ~/.local/state/b10x/plan.json compares both the plugin and CLI with current releases. Use the corresponding host, inspect the plan and apply within the user's authorization. An unresolved release check is reported as unchecked.

Moving from 0.7.x changes CLI and configuration contracts. Preserve the old state, inspect the consumer operations, then establish current connections through protected acquisition. No v1 configuration or credential migration occurs automatically. After any upgrade, inspect help, check prerequisites and validate the operations the application actually needs.

Since v0.32.0, --output json carries an invocation's provider result and each operation's input and output schemas as JSON values rather than JSON text; a caller that decoded them twice reads them directly. The upgrade also moves the configuration revision of instances using the shipped GitLab selection set: print the bootstrap again, revalidate their connections and issue their approval policies again, as the skill's setup reference describes.

Since v0.33.0, setup init creates a metadata store that v0.32.0 and earlier refuse to open, so upgrade every binary that opens a store before using a new one. An existing store keeps working with older releases until its owner runs the one-way setup checkpoints-enable --confirm one-way.

Since v0.34.0, a connection saved under an earlier configuration revision answers revalidate_connection when it can follow the new revision and create_connection otherwise, never retry_status. Since v0.36.0, a local read whose deadline passes after it was sent reports timeout at stage = dispatch, and an invoke whose answer never arrives reports outcome_unknown.

Since v0.39.0, a catalog selection may name credential parameters, which are never sent; a release before v0.39.0 refuses such a selection file, so upgrade every binary that loads the adapter first.

From v0.41.0 to v0.43.0, the shipped catalog selection sets use members that earlier releases refuse, and the GitLab, Jira and SQL descriptors gain operations. Upgrade every binary that builds or loads the adapter first. An existing adapter entry keeps the operations it permits. An instance that takes a shipped selection set or GitLab bundle from the new release has a new configuration revision; recover as the setup reference describes.

In v0.44.0 the GitLab selection set grows from 42 to 51 operations, and in v0.45.0 the Slack bot set from 7 to 10 and the Jira set from 8 to 9; each has a new configuration revision, so copy it again from the adapter's bootstrap output and add new operations to the adapter's operations only when they are authorized. Since v0.44.0 a source amendment may correct a request media type (correct_media_type). Since v0.45.0 a catalog connection may admit further origins in hosts for binary reads such as Slack file downloads, which changes its revision, and a Kubernetes configuration may enable pod_logs, kubeconfig and pod_exec. Pod exec is a write on the connectors-private/2 exchange and needs an approval policy like every write.

Since v0.46.0 setup check reports the build's os and its custody_backend. In v0.47.0 the Slack bot set gains two writes under approval, conversations.open and chat.postMessage, and a catalog guard can expect a JSON boolean ({"boolean": true}). The same release refuses a guard written {"literal": "true"} or {"literal": "false"} when the selection loads: a configuration that carries its own selection file rewrites each as {"boolean": …} when it upgrades the binaries that load it. Since v0.48.0 the CLI and its local host run on macOS, with weaker platform guarantees than on Linux, and releases carry prebuilt archives.

v0.60.0 removes operations invoke and the top-level service commands (describe --endpoint, invoke --endpoint, serve); each is now a parse refusal, so a script that called them is rewritten to connectors invoke <connector>[/<instance>] <operation> or to HTTP. Instance listings no longer carry adapter. From v0.63.0 an MCP client reads a tool's operation output schema from _meta, and selections that declare a page walk move their configuration revision. v0.65.0 makes setup init write connectors-local/5; setup migrate --mode apply moves a connectors-local/2 file with no legacy entries to it. Its archives also carry the Grafana, Prometheus, Loki and Kubernetes provider programs.
