Anyshift Agent Plugin

A portable Agent Plugins 1.0.0 package that gives compatible agent clients fast, deterministic, read-only production evidence from Anyshift over MCP 2026-07-28.

The package combines one Agent Skill with a Streamable HTTP MCP configuration. It embeds no token, authorization header, project identifier, or database name. Compatible clients discover OAuth, collect consent for one Anyshift project, and store credentials themselves.

Status

Published versions are listed in GitHub Releases, and each package release remains gated on production verification of its matching Graph API support. The portable package validates against Agent Plugins 1.0.0. Since v0.3.0 the production endpoint serves the Anyshift event-graph tool surface — discovery of all ten tools (describe_schema, find_resources, get_resource_details, get_resource_events, get_recent_events, get_correlated_events, get_related, query_graph, list_projects, set_project). v0.3.2 was verified against production on Claude Code on 2026-09-09 with backend v0.94.47 (the AWS open-security-group recipe: 50 rows, securityGroupId on every row, three distinct groups named default correctly kept apart by VPC; see Compatibility evidence). The v0.2.x rows there were captured against the previous catalog surface and are retained with that boundary stated.

MCP protocol compatibility

The production endpoint at https://api.anyshift.io/mcp/graph supports the stateless Streamable HTTP transport defined by MCP 2026-07-28. Modern requests are self-contained and carry the negotiated protocol version, client metadata, method, and tool name on every request. The endpoint also retains legacy MCP compatibility through 2025-11-25 for clients that still use initialization negotiation.

Authorization follows the MCP HTTP authorization profile: the server publishes OAuth protected resource metadata, challenges unauthenticated requests, and binds the resulting graph:read grant to one user-selected Anyshift project.

Capabilities

• discover the project's live graph vocabulary (describe_schema);
• resolve ambiguous infrastructure resources to stable identifiers;
• inspect a resource's properties, relationships, and change-event history;
• sweep windowed project-wide events and reconstruct correlated incident chains;
• traverse the graph neighborhood of any resource; and
• run bounded read-only Cypher for any analysis without a dedicated tool, including the named recipes in skills/agent-plugin/references/recipes.md (event histograms, SPOF fan-in, orphans, co-tenancy, deploy-impact, bounded blast radius, public exposure trace, shortest path, RBAC reach, Kubernetes hygiene gaps, hotspots).

This plugin supplies production graph evidence to an agent already doing a task. It is not an autonomous SRE agent and does not contain an incident-response loop.

Install

Agent Plugins clients can load this repository root directly. They discover the portable plugin.json, mcp.json, and skills/ components. OAuth and project consent are handled by the client; the package contains no credentials or project identifiers.

Codex CLI

Codex 0.147.0 or newer is recommended. Install the latest verified release:

codex plugin marketplace add anyshift-io/agent-plugin --ref v0.3.2
codex plugin add agent-plugin@anyshift
codex mcp add Anyshift --url https://api.anyshift.io/mcp/graph
codex mcp login Anyshift

To test unreleased development changes instead, register main as an edge marketplace source:

codex plugin marketplace add anyshift-io/agent-plugin --ref main

The stable install command is version-pinned deliberately. Each release updates it to the newly verified tag; package validation fails when the README version falls behind the manifests.

The last two commands are required by Codex CLI 0.147.0 because its plugin installer does not yet launch OAuth for a plugin-owned remote MCP server: codex mcp add registers the endpoint and codex mcp login opens the browser OAuth flow; select the Anyshift project the plugin may read. Start a new Codex thread after installation so the skill and MCP tools are loaded together.

Codex CLI 0.147.0 may also log an Auth required warning for the unauthenticated portable MCP entry while using the explicitly registered authenticated connection. Tool discovery and calls are unaffected; no unauthenticated request can read graph data.

Cursor

Cursor 3.15.6 or newer is recommended. Cursor supports Agent Plugins and remote Streamable HTTP MCP with OAuth.

Cursor Marketplace

One-click install from the Cursor Marketplace is coming. Until that lands, use the local Agent Plugin package below.

Local Agent Plugin package

Install the portable Agent Plugin package so Cursor loads the skill and MCP configuration together:

git clone https://github.com/anyshift-io/agent-plugin.git \
  ~/.cursor/plugins/local/agent-plugin

Reload the Cursor window (Developer: Reload Window). Cursor discovers Agent Plugins from ~/.cursor/plugins/local. Authenticate when Cursor prompts (needsAuth / mcp_auth), select the Anyshift project the plugin may read, and start a new agent chat so the Graph tools are available.

Do not symlink a checkout from outside ~/.cursor/plugins/local into that directory. Cursor 3.15.6 rejects out-of-tree local plugin symlink targets and skips the package.

Uninstall (Cursor)

1. Delete ~/.cursor/plugins/local/agent-plugin.
2. Reload the Cursor window.

Cursor caveats

• Local plugin symlinks whose target is outside ~/.cursor/plugins/local are rejected.
• While unauthenticated, Cursor may expose a client-side mcp_auth helper alongside the Graph tools. That helper is not part of the Graph API tool surface.
• The portable package mcp.json keeps the Agent Plugins type: "streamable-http" form for cross-client portability; Cursor accepts that package form when loading the local Agent Plugin.

Usage attribution

Compatible Agent Plugin clients send a fixed, non-secret package name and version with Graph MCP requests. Anyshift uses this declaration for aggregate product usage and reliability telemetry in PostHog and request diagnostics in Sentry. It is not used for authentication, authorization, tenant selection, or rate-limit identity, and the package contains no credentials.

Codex CLI 0.147.0 installs the skill but requires a separate codex mcp add command. That separately configured connection may not forward the package headers, so Anyshift can identify the Codex MCP and OAuth clients without claiming exact plugin attribution for those requests.

On Cursor, the local Agent Plugin package sends package attribution headers by default.

Resource identity

Graph resource names are not globally unique. For example, one deployment name can identify both a Terraform STATE_RESOURCE and the runtime ECS_SERVICE it manages. For short, overloaded, or same-named resources:

1. call find_resources;
2. select the candidate with the intended resource type; and
3. pass that candidate's hashedID from find_resources to the drill-down tools (get_resource_details, get_resource_events, get_related).

An unqualified name-only query remains deterministic, but it can select a different same-named resource kind. Using the resolved stable identifier preserves the selected identity without placing project IDs, database names, or credentials in tool arguments.

Claude Code

Install natively through the plugin manager (bundles the MCP server and the skill in one step):

/plugin marketplace add anyshift-io/agent-plugin
/plugin install anyshift-graph@anyshift

Then run /mcp, pick plugin:anyshift-graph:Anyshift and choose Authenticate (or, from a shell, claude mcp login plugin:anyshift-graph:Anyshift): sign in and select the project the agent may read. The skill is available as /anyshift-graph:agent-plugin and is also picked up automatically. The manual clone + symlink + claude mcp add flow documented at docs.anyshift.io keeps working, but does not receive managed updates.

Validate

npm ci
npm run validate

The validator loads the immutable canonical Agent Plugins 1.0.0 schemas, checks the complete package layout, rejects symlinks and credential-bearing MCP configuration, and verifies the skill's untrusted-data boundary. It also enforces repository-owned contracts for the Codex plugin manifest, marketplace metadata, and skills/agent-plugin/agents/openai.yaml.

Release

After updating every version-bearing manifest, attribution header, lockfile field, and the stable README install ref, publish from main through the guarded workflow:

release_tag="v$(node -p "require('./plugin.json').version")"
gh workflow run release.yml \
  --repo anyshift-io/agent-plugin \
  --ref main \
  -f tag="$release_tag"

The workflow does not choose or bump the version. A read-only job runs tests, package validation, and tag-aware integrity checks without a persisted Git credential. Only its verified tag and exact main commit SHA cross into the isolated publishing job, which executes no package code, refuses existing tags/releases, creates the GitHub release, and verifies the published tag resolves to that SHA.

Cursor on Linux (v0.2.x surface)	3.15.6, ~/.cursor/mcp.json remote URL + OAuth	Pass	Pass	Six catalog tools discovered	get_recent_changes passed	2026-08-11

The v0.2.x rows were captured against the previous catalog tool surface and are retained as transport/OAuth evidence only. Clients other than Claude Code have not yet been verified against the event-graph surface — each requires a fresh recorded check (client version, OAuth discovery, initialization, discovery of all ten tools, one authenticated query_graph call) before its row is upgraded. Tokens, OAuth client identifiers, project identifiers, and customer resource names are intentionally excluded from this record.

VS Code, GitHub, Claude, and other compatible clients remain unverified until their exact client version, installation path, OAuth discovery, initialization, tool discovery, one tool call, and uninstall behavior are recorded.

Security and data handling

• The plugin and MCP tools are read-only.
• OAuth grants are scoped to one user-selected Anyshift project.
• Credentials are discovered and stored by the client, never embedded in this repository.
• Graph strings are untrusted data and must never be followed as instructions.
• Absence of graph evidence is not proof that a resource, dependency, or change does not exist.
