How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified

Background: How many MCP packages publish verified provenance →
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
jade.apply ~155
Apply several edits as one atomic unit: all land or none do. Ops: replace_text, replace_range, replace_symbol, delete_symbol, insert. Anchors are validated before anything is written, touched files are formatted, and one validation runs at the end instead of one per edit. Prefer this over several single edits when changing more than one site.
| Name | Type | Req | Description |
|---|---|---|---|
| check | string | – | Run one validation after all edits: build, typecheck, tests (the edited files' tests), or impact (those plus tests of callers of touched declarations). |
| edits | array | yes | Edits to apply in order. |
| expectedRevision | string | – | Revision expected before editing. |
| format | boolean | – | Format touched files afterwards (default true). |
No output schema declared.
No examples provided.
jade.check ~227
Run a validation command on demand and wait for the verdict: kind build (default), typecheck or tests. Uses the repository's own Makefile target, npm script or cargo command when present. Waits by default and returns pass/fail directly. Every result names the command that ran; dryRun names it without running anything. In a repository with several projects, pass target to check one; with no command at the root, the answer lists the projects.
| Name | Type | Req | Description |
|---|---|---|---|
| dryRun | boolean | – | Name the command that would run, without running it. |
| kind | string | – | build (default), typecheck, tests, lint or codegen. lint and codegen run the declared commands of that kind; lint with none declared runs typecheck. |
| target | string | – | Project directory inside the workspace to check, e.g. services/api. Omit for the workspace root. |
| timeoutSeconds | integer | – | Bound on the wait (default 90, max 300). |
| wait | boolean | – | Wait for the result (default true). False returns a job ID to poll. |
No output schema declared.
No examples provided.
jade.create_file ~59
Create a brand-new file, and any missing parent directories. Refuses to overwrite an existing one — use replace_text or apply to modify existing content.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | File content. |
| path | string | yes | File path to create. |
No output schema declared.
No examples provided.
jade.declare_command ~149
Declare a named command in .jade/commands.json — a reproduction, a benchmark — to run with run_command in this and later sessions; the file is reviewed like any change. Declaring an existing name replaces it; do not redeclare one just to run it.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | – | Optional note on what the command is for. |
| kind | string | – | Optional: lint or codegen; check with that kind runs it. |
| name | string | yes | Command name: lowercase letters, digits, ':', '_' or '-'. |
| remove | boolean | – | Delete the named command instead of declaring it. |
| run | string | – | Shell command to run from the workspace root. |
No output schema declared.
No examples provided.
jade.delete_file ~54
Delete a file, not a directory; fails if it does not exist. Reverting to an earlier checkpoint recreates it. To edit content use replace_text or apply.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | File path to delete. |
No output schema declared.
No examples provided.
jade.find ~262
Locate declarations by name AND return their source in one call — the fused search-and-read that replaces `grep -n 'func X' -A 30`. Exact name matches win over substring ones. Use this instead of outline and read_range when you have not located the symbol yet. Pass queries to find several names in one call.
| Name | Type | Req | Description |
|---|---|---|---|
| budget | integer | – | Size of the answer in tokens. Cut at whole declarations; the rest is behind continue=<handle>. |
| continue | string | – | Handle from a cut answer: its next page. |
| dependency | string | – | Look in this dependency's source instead of the workspace, read-only: a crate, Go module, npm or Python package name. |
| kind | string | – | Narrow by kind. func/function, type/struct/class/interface, method, const, var — spellings within a family are equivalent. Empty matches any. |
| limit | integer | – | Maximum declarations to return (default 5). Prefer budget. |
| maxLines | integer | – | Maximum lines of each body (default 40). Prefer budget. |
| queries | array | – | Several symbol names in one call, instead of query. Each is answered as query would be. |
| query | string | – | Symbol name, exact or partial. |
No output schema declared.
No examples provided.
jade.grep ~356
Literal or regex text search across the workspace, returning path:line matches with optional trailing context — the replacement for `grep -rn`. Use this for anything that is not a declaration name: struct fields, string literals, error messages, config keys, or any search needing a path filter. Use find instead when you want a declaration and its body. Pass queries to search several patterns in one call.
| Name | Type | Req | Description |
|---|---|---|---|
| budget | integer | – | Size of the answer in tokens. Cut at whole matches; the rest is behind continue=<handle>. |
| context | integer | – | Trailing lines to show per match, like grep -A (max 40). |
| continue | string | – | Handle from a cut answer: its next page. Other arguments except budget are ignored. |
| dependency | string | – | Search this dependency's source instead of the workspace, read-only, at the version the project locks: a crate, Go module, npm or Python package name. Matches read as dep:<name>/<path>, which read_ra… |
| exclude | string | – | Skip paths containing this substring, e.g. testdata. |
| glob | string | – | Restrict by path, e.g. *.go or internal/code/*. |
| ignoreCase | boolean | – | Case-insensitive match. |
| limit | integer | – | Maximum matches returned (default 40). The true total is always reported. Prefer budget. |
| queries | array | – | Several patterns in one call, instead of query. Each is answered as query would be, with the same filters. |
| query | string | – | Text to find. |
| regex | boolean | – | Treat query as a regular expression. grep-style \| alternation and \( \) groups work as in grep. |
No output schema declared.
No examples provided.
jade.insert ~225
Add text to a file without replacing anything — a new function, a new section, an extra case. Use this for additive work instead of rewriting a surrounding symbol. With no anchor it appends to the end of the file; with one it places the text before or after that anchor, refusing if the anchor is absent or matches more than once. Several additions or edits at once belong in apply.
| Name | Type | Req | Description |
|---|---|---|---|
| anchor | string | – | Optional. Exact, unique text to place the insertion beside. Omit to append to the end of the file. |
| expectedDigest | string | – | Optional. The digest from the read this edit is based on; the edit is refused if the file changed since, by anyone. |
| expectedRevision | string | – | Optional. Revision expected before editing; the edit is rejected if the workspace has moved on. Omit for no precondition. |
| path | string | yes | File to add to. |
| position | string | – | Optional. "before" or "after" the anchor. Defaults to after. |
| text | string | yes | Text to insert. |
No output schema declared.
No examples provided.
jade.read_range ~273
Read a file verbatim, whole or by line range — the replacement for `cat` and `sed -n`. Omit both line numbers to read the whole file, which is how to read go.mod, a Makefile, or any JSON/YAML/TOML config that has no symbols to address. An end line past the end of the file reads to the end. A dependency's source reads as dep:<name>/<path>, read-only. Several ranges, in one file or many, go in one call: {"ranges": [{"path": "a.go", "lines": "280-400"}, {"path": "b.go", "lines": "700-760"}]}.
| Name | Type | Req | Description |
|---|---|---|---|
| budget | integer | – | Size of the read in tokens (default 5000). Cut at whole lines; the rest is behind continue=<handle>. |
| continue | string | – | Handle from a cut read: the rest of it. |
| lines | string | – | Line range: "280-400", "280-" to the end, or "280". Omit to read the whole file. |
| path | string | – | Repository-relative or workspace-relative file path. |
| ranges | array | – | Several reads in one call, instead of path. A range that fails reports its error without failing the others. |
No output schema declared.
No examples provided.
jade.replace_text ~172
Replace an exact, unique string in a file. An anchor string does not move when the lines around it do, which is why follow-up edits address text rather than line numbers. Refuses when the anchor is absent or matches more than once — extend it with surrounding context to disambiguate. For several sites, use apply: atomic, one validation, no diagnostics from half-done intermediate states.
| Name | Type | Req | Description |
|---|---|---|---|
| expectedDigest | string | – | Optional. The digest from the read this edit is based on; the edit is refused if the file changed since, by anyone. |
| expectedRevision | string | – | Revision expected before editing. |
| newText | string | yes | Replacement text. |
| oldText | string | yes | Exact text to replace. Must appear exactly once. |
| path | string | yes | File path to edit. |
No output schema declared.
No examples provided.
jade.run_command ~123
Run a command the repository declares, by name, and wait for the verdict: pass/fail with the decisive output. Use it instead of a shell for anything check does not cover. No name lists the declared commands. Nothing fits? declare_command it once.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | – | Declared command to run. Omit to list the declared commands. |
| timeoutSeconds | integer | – | Bound on the wait (default 90, max 300). |
| wait | boolean | – | Wait for the result (default true). False returns a job ID to poll. |
No output schema declared.
No examples provided.
jade.run_tests ~177
Rerun a failing test, a test file, or changed files' tests; waits for pass/fail and the first failure. Full suite: check kind tests.
| Name | Type | Req | Description |
|---|---|---|---|
| file | string | – | Test file to run, for scope=file (Go: its package). With scope=test, limits the name filter to this file. |
| scope | string | – | all (default), file, test or changed. |
| test | string | – | Test name, for scope=test: exact in Go, the runner's name filter elsewhere (jest/vitest -t, ava --match, pytest -k, cargo test <name>). |
| timeoutSeconds | integer | – | Bound on the wait (default 90, max 300). |
| wait | boolean | – | Wait for the result (default true). False returns a job ID to poll. |
No output schema declared.
No examples provided.
How do I install the Jade MCP server?
Jade ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.
mcpb · jade-mcp_v0.0.11.mcpb
Download bundleThe MCP registry declares no SHA-256 for this bundle, so there is no published digest to check it against. Open it with an MCPB-capable host such as Claude Desktop.
What is the Jade MCP server?
Jade is an MCP server listed in the public MCP registry as io.github.julianbei/jade. The IDE for agents: read by symbol, edit against a revision, validate with your own build, revert. This page covers its MCPB bundle (https://github.com/julianbei/jade/releases/download/v0.0.11/jade-mcp_v0.0.11.mcpb).
Is the Jade MCP server safe to use?
Jade scores 45 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Jade MCP server expose?
Jade exposes 12 tools: jade.read_range, jade.find, jade.insert, jade.replace_text, jade.create_file, and 7 more. Their descriptions and schemas cost roughly 2,232 tokens of context every time the server is loaded.
Is the Jade MCP server still maintained?
Jade is marked deprecated in the MCP registry. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Jade MCP server under?
Jade declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
